138mm (132mm Finished) Standard Softwood Internal Door Lining Set

138mm (132mm Finished) Standard Softwood Internal Door Lining Set is a practical and cost-effective solution for forming a complete internal door frame, particularly suited to 100mm (4”) blockwork walls with plasterboard and plaster. Manufactured from responsibly sourced softwood, this lining set provides a stable and durable base for hanging internal doors and achieving a clean, professional finish.

Supplied unfinished, the door lining can be painted, stained, or varnished to suit your interior décor. A separate loose door stop is included, allowing it to be fitted after the door has been installed for accurate alignment and a neat final appearance. Door furniture is not included.

The reversible head design makes this internal door lining suitable for both 762mm and 838mm doors, the most common UK internal door sizes. This flexibility makes it ideal for new builds, refurbishments, and replacement door projects.

Manufactured from PEFC-certified whitewood spruce, this internal door lining is designed for interior use and offers a reliable balance of strength, consistency, and ease of installation. Suitable for both professional installers and DIY users.

Each lining set includes two uprights, one head, and loose door stops, with assembly required.
