SpeedSet Plus

SpeedSet Plus is a revolutionary adjustable internal doorset, exclusive to Premdor. This prefabricated doorset is suitable for both new build and renovation projects and has been designed to significantly reduce door installation times to just 20 minutes.

The SpeedSet Plus doorset system also allows for easy adjustment to accommodate variations within a given wall thickness (now up to 300mm); a common problem encountered on-site, resulting in delays and extended completion dates.

The SpeedSet Plus doorset is suitable for a wide-range of applications and is also available as an FD30 fire door option.

SpeedSet Plus doorset kit includes: Doors (choose from the Premdor interior door range) are factory pre-hung on CE marked adjustable chrome effect or white hinges. Doorset also includes factory fitted CE Marked door latches and white recoatable foil-faced finish frame and pre-mitred architrave that require minimum on-site decoration (Pencil Round, Ogee and Torus architrave styles available).
