Door Frame Kits

Single Glazed Doors

Our double glazed door frame kits include traditional and slimline options.

As an additional option, you can also order slimline aluminium door frames fabricated at the same time as your single glazed door, enabling both door and frame to be perfectly aligned to fit together quickly on-site.



Comprehensive Service

All of our door frame kits come complete with all the items you could require to install our Ultima doors. The kit includes hinge post, strike leg, head post, shoulder brackets, gaskets, base brackets and strike plates.Our frames are suitable for use with a drylining wall or a glass wall, and the design affords quick on-site installation.

The frame includes a glazing pocket designed into the section to allow you to glaze straight out of the back of the frame, reducing the number of profiles required to install on-site. All of our door frame extrusions are held in stock in large quantities in 4 primary colours. These are Black RAL9005, Anthracite Grey RAL7016, Grey RAL9006 and White RAL9010. We also have custom paint options for our door frames and can paint in any of the RAL colours currently available in the RAL range.



Custom Fabrication

Our frames are custom fabricated to order and machined at our facility in Tipton, allowing us to control our production process and keep lead time to a minimum.
