The knockdown steel frames from the “CM” series, manufactured by Métalec, are designed to be installed once the partition is in place.

The double return of the knockdown steel frame enables a close fit without damaging the wall finish.

Six tension anchors allows an adjustable installation on each frame ensuring a solid binding and a true alignment. The two strap anchors are welded at the bottom of the jambs. The knockdown frames takes a few minutes to install and can be relocated, if necessary, without damage.
