Jackson's : Museum 44in Center Bar : 20x65mm : For 35mm Deep Bars : With 1 Notch

These Jackson’s Museum Center Bars have a depth of 20mm and are designed to fit the 35mm deep stretcher bars.

Jackson’s Museum Center Bars assemble to make solid professional stretchers for canvas that are free from twisting or warping. Made from 100% PEFC-certified pine, the wood is first kiln-dried to remove all moisture. The pieces are then finger-jointed and triple-laminated. This removes the natural tendency of the wood to twist or warp due to changes in heat and humidity. The result is a solid, professional-quality stretcher system.

Stretcher bars are sold in pairs, while crossbars and center bars are sold singly. Center bar slots are included only on stretcher bars measuring 24in or longer. Center bars 40in or longer feature a central notch, allowing crossbars to sit flush in a lap joint, providing extra support for larger canvases. Stretcher bars measuring 84in and over have two center bar slots for extra stability. Remember, when purchasing center bars, to match their length to the length of the shorter side of your canvas (i.e. the side parallel to the center bar).
