What is a Spacer Plate?
A spacer plate is a slim frame that sits between your electrical back box and the faceplate of a light switch or plug socket. It fits over the standard fixing holes, so the same screws hold everything together, without having to excavate the wall.
In short, it sets the faceplate at exactly the right distance from the back box. That solves two very common problems: a back box buried too deep behind new tiles or plaster, and a faceplate with no room behind it for the wiring. Both are covered below.

Fire-Retardant ABS, Not PLA or PETG
All of our spacers are printed in Sunlu FR-ABS, a UL94 V0 flame-retardant ABS built for parts that sit right next to live wiring. Many competitors print in standard PLA or PETG, which are not rated as fire-safe and can contribute to the spread of a fire if something behind the faceplate goes wrong.
Self-Extinguishing
UL94 V0 rated: the material stops burning within seconds of the ignition source being removed, for fire-critical applications like electrical fittings.
High Impact Strength
Up to 14 kJ/m² of impact resistance, for a tough, long-lasting part that stands up to knocks during and after fitting.
Stable Under Heat
Low warping and strong layer adhesion, with reliable performance up to 86.5°C, well beyond what a spacer will ever see behind a faceplate.
Two Problems, One Simple Fix
Whether your back box is buried too deep or simply too full, a made-to-measure spacer gets the faceplate sitting exactly where it should.
The Back Box Sits Too Deep
Tiling or re-plastering builds the wall surface outward, leaving the back box recessed below it. The faceplate is either sunken behind the new wall surface, or has nothing to sit against, so it tilts or wobbles. The spacer bridges that gap, letting the faceplate sit perfectly flush. Once fitted, the spacer is completely hidden behind the plate.
Not Enough Room for the Wiring
Sometimes the box is already level with the wall, but there is not enough space behind the faceplate for all the wires to fit, so it bulges or will not screw down flat. This is a common issue when fitting slimline faceplates or smart switches. The spacer brings the faceplate further out, creating extra room behind it for the wiring or switch hardware.
Why Choose a Custom Spacer?
Off-the-shelf spacers come in fixed depths. Real installations don't. Our made-to-order spacers fit perfectly every time.
Any Depth You Need
Specify the exact depth from 2mm to 30mm. No more hunting for the right size at DIY stores.
Custom Width & Height
Single gang, double gang, large multi-gang - or any custom dimension to match your specific faceplate.
Corner Radius Control
Square corners or a soft radius - choose the profile that matches your existing faceplate and aesthetic.
Fixing Lugs
Add integrated fixing lugs for a more secure installation - or remove them when not required.
Fire-Retardant Material
Printed in UL94 V0 flame-retardant Sunlu ABS-FR, not PLA or PETG, so it self-extinguishes if things go wrong behind the faceplate.
Fast Delivery
Made to order and shipped quickly. Perfect for tradespeople who can't afford to wait weeks for a specialist part.
