HOW TO INSTALL AN EXPANDABLE FRAME
Frame jambs have corner tabs spot welded at the seam which interlock with slots on the frame head. This product is then bent over to pull the corners at the head and jamb legs, creating a tight joint.
The frame faces are dimpled in three locations on the jambs and two locations on the heads, allowing for screw fastening of the frame to the wall.
Bondo screw holes after installation, before painting.
Fire rated from 45 up to 90 minutes (Single Drilled Only)
The frame has an interlocking header that attaches to the jamb legs and is fixed into place with drywall screws when the frame is installed against both sides of the wall. The frame has two frame face dimple locations on the jamb legs and one in the centre of the header, as well as two holes to attach the header to the frame. There are no anchors rewuired for the EFK frame. The bottom dimple holes on each side screw to the drywall frame to ensure its stability.
