38 x 115MM FIRE CERTIFIED DOOR LINING SET WITH STOPS AND 15 X 4MM GROOVE 2'6"/2'9"

What is included and who it is for

This is a complete door lining set, meaning it arrives as a pre-assembled frame with stops already fitted. The integrated 15 x 4mm groove is designed to receive door seals or weatherstripping where needed. The fire certification makes this product essential for properties subject to building regulations that mandate fire safety performance in doorways—typically hallways, escape routes, and communal areas. It suits trade installers, builders, and competent DIY customers familiar with door frame installation.

Pre-assembled frame with stops included
15 x 4mm groove for seals or weatherstripping
Fire certified to meet building regulations
Suitable for standard plasterboard wall construction

Sizing and compatibility

The frame is supplied in two height options: 2'6" (762mm) and 2'9" (838mm). These are standard UK door heights designed to work with corresponding door leaf sizes. The 38 x 115mm profile is engineered to fit into typical cavity wall and solid wall openings where plasterboard finish is applied. Before ordering, confirm your wall opening dimensions and the height of the door you intend to hang. Check that your wall thickness falls within the tolerance of the 115mm depth to ensure proper fit and finish.

Pre-installation checks

Inspect the lining set on delivery for any damage, warping, or defects that could affect installation. Check that the frame is square by measuring diagonals—they should be equal. Ensure the stops are securely fixed and the groove is clear of debris. Confirm the wall opening is plumb and square, and that any existing frame has been cleanly removed. Prepare the opening by making good any damage and ensuring the surface is clean and dry. Have your door leaf, hinges, and hardware ready before fitting the frame.
