This is a pair of Jackson’s Museum Stretcher Bars with a profile dimension of 20 x 50mm, offering professional strength and stability for building custom canvases.
Crafted from 100% PEFC-certified pine, the wood is first kiln-dried to remove all moisture. It is then finger-jointed and triple-laminated, which eliminates the natural tendency of wood to twist or warp due to changes in heat and humidity. Laminated wood provides greater strength and stability than finger-jointed or solid wood.
Stretcher bars measuring 50cm and over have centre bar slots. Centre bars 100cm and larger will have a notch cut in the centre, allowing crossbars to sit flush in a lap joint, providing extra support for larger canvases. Matching Jackson’s Museum Centre Bars are available with a 16mm profile for these 20mm deep stretcher bars. Centre bars are sold individually.
