44x74mm STANDARD FRAMES & SIDELIGHTS
Standard size for frames is 44x74mm cross section, with rebate suitable for 40mm thick doors. Internal dimensions are 762/ 813/1206/1511/1614mm with internal height of 2032 (cut to 2080) mm. Timber used is imported meranti – no veneers, laminations or finger-joints in the standard frames.
We can also supply customised frames with the above cross-section dimension (eg for 2400mm door height).
We pre-treat frames to ensure that they are protected from damage and staining during the building process. Once installed, the frames can be re-treated to keep their natural wood finish or painted with PVA or enamel (a suitable primer is recommended) to suit the needs of the individual.
