75" window display · floor-anchored

Install a window display, crate to content

A 75-inch tempered glass display, 82 kg, standing on two rails bolted into the floor. This covers the whole job: what to bring, how the anchor pattern is set out, the order the work has to run in — which matters more here than on most installs — and how to confirm it is finished properly.

Manufacturer's assembly drawing of the 75-inch window display shown from five angles: the bracket from above with rails 1001 mm apart, a side view with four anchor holes at 300 mm spacing, the front elevation giving 2177.7 mm overall height and a 500 mm gap below the screen, an edge view showing 89.2 mm depth, and the rear panel with its vents and fans.
The unit as built, with the dimensions that decide where it can go. Overall height is 2177.7 mm, the glass starts 500 mm off the floor, and the whole assembly is only 89.2 mm deep — measure the reveal before the crate arrives.

01Before the Visit

Two things decide whether this job takes two hours or gets abandoned: the floor, and whether a second pair of hands is available.

What you bring

What is in the crate

The supplied accessory kit laid out on a bench: a remote control, a stubby Wi-Fi antenna, a power plug, two keys on a ring, black plastic caps and feet, eight large M12 expansion bolts, a bag of smaller bracket screws and a hex key.
Everything that ships with the unit. Count the expansion bolts before you start — there are eight, and the unit is not secured until all eight are in.
Keep in mind The screen surface has no protective layer. Keep the display in its crate until marking and drilling are finished, so dust and tools stay away from the glass.

02Floor Types

The anchor spec assumes a concrete slab. Establish what the floor actually is before the day — it decides which bits are needed, and in one case whether this bracket can be used at all.

FloorWhat it means
Bare concreteThe standard case. Masonry bit, hammer action on.
Tile over concreteBring a tile or ceramic bit as well. Break the glaze at low speed with hammer action off, then switch to masonry for the slab. A masonry bit used from the start chips the tile face, and the chip stays visible.
Timber, raised or hollowDo not proceed on the supplied expansion bolts — they need solid material to expand into. What replaces them depends entirely on what is underneath, so this needs settling before the unit is on site, not on the day.
Tiled shop floors A window display sits in the most visible square metre of the store. A cracked tile at the base is permanent and it is the first thing the owner sees. Slow down for the first 5 mm of every hole.

03Set Out the Anchor Pattern

Nothing is adjustable once the bolts are set. Everything that needs checking gets checked now.

Plan view of the anchor pattern: two parallel mounting rails set 1001 mm apart axis to axis, each with four 16 mm holes spaced 300 mm centre to centre, eight holes in total.

  1. Mark the two rail axes 1001 mm apart.
  2. Mark four holes per rail at 300 mm centres.
  3. Check square, check level, and check the diagonals match before any bit touches the floor.

Check the sightline At 2177.7 mm overall the unit is taller than most shopfront mullions and door heads. Hold a tape up at the marked position and look at it from the pavement before drilling — this is the last moment the position can move.

04Assemble the Screen to the Bracket

On the floor, flat, before anything is raised. Doing this after the raise means holding 82 kg of glass with one hand.

The bracket rail screws to the back of the cabinet with the supplied screws. Both rails go on while the assembly is still flat.
  1. Lay the display face-up, or face-down only on a padded surface.
  2. Offer each bracket rail up to the back of the cabinet and drive the supplied screws home with the hex key.
  3. Fit both rails, then check the assembly sits square before it goes anywhere near the drilled holes.
The glass is unprotected Do not rest the display face-down on an unpadded floor, do not slide it, and keep tools off the glass. A scratch here is not repairable — it is a replacement panel shipped from the factory.

05Drill All Eight Holes

All eight, before the unit is raised. This is what makes the raise short and what makes a one-person raise survivable if it comes to that.

  1. Drill each hole 16 mm diameter, at least 110 mm deep. Mark the depth on the bit with tape if it has no stop.
  2. On tile: ceramic bit, low speed, hammer off until the glaze is through. Then masonry bit, hammer on.
  3. Vacuum or brush every hole out. Dust left in the hole stops an expansion bolt seating properly.

06Raise and Bolt Down

The raise is the single point in this job where the screen gets damaged. Plan it before you lift.

Two hands gripping the vertical bracket rail of the assembled display while it stands upright, with the black screen visible alongside and nobody touching the glass.
Upright and held by the rail, never by the glass. Hands stay on the frame and the bracket throughout the raise.
  1. Two people. One steadies the unit, one starts the bolts.
  2. Raise the assembled unit and align the rail plates with the drilled holes.
  3. Fit all eight M12 expansion bolts and tighten them. The unit is only secured once all eight are tight — until then someone keeps a hand on it.
Never lift this single-handed by choice At 82 kg the raise is where the glass gets broken. If you are alone: drill all eight holes first, stand the unit straight onto the pattern and start the bolts without letting go. Better still, ask a member of staff to steady it for the minute it takes.

07Cable and Power

The cable leaves through the bracket, not around it.

The cable exit sits at the base of the bracket rail, at floor level. Route the power cable out through it rather than letting it trail across the base.
The connection panel on the underside edge of the display: USB ports, an HDMI port, a network socket, a red rocker power switch and the power inlet with a cable being plugged in.
The inlet and the rocker switch sit together on the edge of the cabinet. The switch has to be on as well as the outlet live — a unit that looks dead is often just switched off here.
  1. Route the power cable out through the exit at the base of the rail.
  2. Connect power and set the rocker switch to on.
  3. The display works on power-up. No hardware configuration is needed at this stage.
Check which rail before you drill The cable exits on one rail only, and that decides which side the outlet needs to be on. Look at the actual bracket while it is still flat on the floor — it is obvious then, and impossible to change once eight bolts are set.

08Get It Playing

A mounted screen with no software is a black panel. About 10 minutes. Each screen has its own activation code, and it is handed over when the screen is ready to take it rather than in advance — so have it to hand before you start this section.

  1. Wi-Fi first. In the Android settings, join the site network and confirm the internet actually works. Nothing below succeeds without it.
  2. Install the player app. Open the download link in the screen's own browser, or copy the installer onto a USB stick and open it with the file manager. In the app list it appears as OnSignage — that is the right app, listed under the vendor's name rather than ours.
  3. Enter the activation code for this screen, exactly as given, hyphens included. Paste it if you can — mistyping is the usual reason it is rejected.
  4. Enable auto-start (auto start / start on boot) so the screen returns to playback by itself after a power cut.
  5. Press GO and confirm content plays.
Done means this Content is playing, and after a full power-off and power-on it starts again on its own, with nobody touching the remote. Test the power cycle before you leave — it is the only check that proves auto-start is really set.
SymptomTry this

09Before You Pack Up

Five minutes now saves an argument later. Once the unit is bolted down and the trim is back, most of this becomes impossible to check without unbolting it again.

  1. Push-pull test. Hand pressure at the top of each rail, front to back. Any movement means a bolt has not expanded properly — find it now, not in six months.
  2. Re-check level on the finished install. A window display sits against vertical mullions and reads crooked from the pavement long before a spirit level says so.
  3. Confirm the power cycle. Switch the unit off at the wall, wait, switch it on, and watch content come back by itself.
  4. Clear the dust. This is a shop floor. Drilling swarf on tile is what the owner remembers.

Worth photographing

Not paperwork — a record that answers questions later, when the screen is against a wall and nothing is accessible.

If something stops the job A floor that turns out to be hollow, a missing bolt, a raise that needs a second person who is not there — these are normal, and stopping is the right call. Leave the unit crated and safe rather than half-fixed, and note what was missing while it is fresh.

10FAQ

Does the unit have to be anchored into the floor?

Treat it as required. The bracket is supplied with eight M12 expansion bolts and the manufacturer's drawing specifies an eight-point pattern, which is the configuration this guide covers. An 82 kg glass panel standing 2.2 m tall in a public doorway is not something to judge by eye — if a site genuinely cannot be drilled, that is a conversation to have before the unit ships, not a decision to take on the day.

How many people does the raise need?

Two. The unit is 82 kg and the glass has no protective layer. One person can manage only if all eight holes are drilled first and the bolts go in immediately, without letting go.

The floor is tiled. Can I drill straight through?

Not with a masonry bit from the start — it chips the glaze, and the chip is permanent and visible. Break the tile with a ceramic bit at low speed with hammer action off, then switch to masonry with hammer on for the slab.

Which side does the power cable come out?

At the base of one bracket rail, at floor level. Confirm which rail before the visit, because it decides which side the outlet has to be on.

Is the job finished once the screen is bolted down?

No. The screen has to be on Wi-Fi, the player installed and activated, and playback confirmed to survive a power cycle. See Get it playing.

Stuck? We'll sort it out.

Send a photo of the floor, the bracket, or whatever the screen is doing — it is usually all we need to answer on the first reply. If something on site does not match this guide, ask before improvising: the awkward cases are almost always the floor, and they are cheap to solve before the drill comes out.

This is the general guide for the model. Anything specific to one site — floor construction, access, where the power lands — is worked out for that installation separately.
