Jackson's : Museum 20cm Centre Bar (15x58mm) : For 35mm Deep Bars

Our new Museum Stretcher Bars will assemble to make solid professional stretchers for canvas that will not twist or warp over time. The key lies in the materials used and the treatments given. Only first class, 100% PEFC Certified pine is used. After the wood is kiln dried to remove all moisture from the raw materials, the pieces are finger jointed and triple laminated. By finger joining the pieces of wood the natural tendency for the wood to twist or warp is eliminated. Triple lamination takes this even further, protecting the wood from changes in humidity in the environment that may otherwise cause wood to expand.

Our stretcher bars are sold in pairs; cross bars and centre bars are sold singly. Any bars which are over 60cm will have a slot into which you can fit a centre bar for extra stability.

Please be aware that our Museum Stretcher Bars are available in two sizes: the larger has a 35mm profile (i.e. it projects out 35mm from the wall). The smaller has a 20mm profile. It is not possible to mix and match: you must ensure that you purchase stretcher bars, centre bars and crossbars with the same profile depth. Remember when purchasing centre bars to match their length to the length of the shorter side of your canvas (i.e. the side parallel to the centre bar).

This is a Jackson's Museum 50cm Centre Bar (15x58mm) for use with the deeper (35mm) profile stretcher bars.
