7235 Adjustable Brace Bar Brackets pack 2

Brace bars minimise the bowing of a larger stretcher frame

When constructing larger stretcher frames for canvas there is often a need to fit brace bars to minimise bowing of the frame. Many LION stretcher bars are notched for ready-made brace bars with tongues on the ends, but for stretcher bars without the notches, these adjustable brackets are ideal.

The alternative method uses moulded brace bar brackets which screw onto the inside faces of opposite stretcher bars. The sockets take brace bars measuring up to 18mm x 44mm. The back face of the bracket is 72mm x 19mm with holes for two screws.

Brackets used in combination with brace bars have a variety of uses:

• Retro-fit to stretched canvases which are bowing

• Fit to stretcher frames that do not have cut-outs for brace bars or where the correct size brace bar is not available

• Add strength to stretcher frames made with stretcher profile in lengths

• Use also to strengthen traditional picture frames where there is sufficient rebate depth

• Oval holes on the sides take screws to hold the profile in and allow for the effective length to be adjusted to tension the frame
