127mm x 90mm, standard strut length. Suitable for mouldings approx 13mm wide. Back and strut of black finish MDF, 1.9mm thick.
Edges and both faces of the strut are black.
The hidden press-fix strut hinge self-locks to the pre-set angle. Strut is positioned so frame can stand either way. To hang, most sizes have two sawtooth hangers, positioned so frames can hang either way.
All press-fix strut hinges can be a little stiff on the first opening. Encouraging users to ease it up with a knife or screwdriver can be helpful.
Sometimes, tiny chips might appear on the edges of the black struts; touch-up with a marker.
