ESSVE Indu-Prog Frame sleeve is designed for installation in frames of wood, aluminium and steel.

Indu-Prog Frame sleeve is a universal frame fixing, which is excellent to work with irrespective of the material the fixing is to be made in. The frame sleeve may either be prefitted on delivery of windows and/or doors or installed directly on site. The wall material, which can be wood, concrete, steel, lightweight concrete, haydite, etc determines the choice of fixing, see the Installation instructions to select a suitable ESSVE fixing. Indu-Prog frame sleeve is made of zinc and is available in two lenghts, 28 and 38 mm. Dimension 28 mm is used for light doors and small windows with joints up to 13 mm and in aluminium or steel sections. Dimension 38 mm is used for massive doors, exterior doors and larger windows or joints up to 23 mm. The outside Indu-Prog frame sleeve consists of a 20 mm hex plate and the M16 threaded fixing section. The M16 thread means the frame sleeve is ideal for aluminium and steel frames as well as frames of wood. Inside Indu-Prog Frame sleeve is an internal 10 mm hex.

Pre-drilled 14 mm holes are required for installation in wooden frames. The grooves on the underside of the external hex plate allow countersinking in the frame. In thin pre-drilled aluminium sections, the ESSVE Indu-Prog Frame sleeve cuts its own thread. For steel frames, an M16 thread is required in the hole.
