Jackson's : Museum Wooden Stretcher Bars : For 35mm Deep Bars

<p>Jackson’s Museum Wooden Stretcher Bars offer a professional, sustainable solution for artists who wish to build their own canvases. Made from layers of laminated wood, they assemble into solid stretchers that resist twisting or warping.</p><p> The stretcher bars are 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.</p><p>These Jackson’s Museum Wooden Stretcher Bars are 35mm deep and 58mm wide. They are sold in pairs. Matching center bars are available with a 20mm profile. Center bars are sold individually. When ordering, ensure that all components (stretcher bars, center bars, and crossbars) have the corresponding profile depth. <p>Stretcher bars measuring 24in and over have center bar slots. Center bars 40in and larger will have a notch cut in the center, 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. Matching Jackson’s Museum Center Bars are available with a 20mm profile for these 35mm deep stretcher bars. Center bars are sold individually. </p><p>For more in-depth information on stretcher bars, read <a href="https://www.jacksonsart.com/blog/2018/09/13/everything-you-need-to-know-about-stretcher-bars/" target="_blank"><span style="text-decoration: underline;"><strong>Everything You Need to Know About Stretcher Bars</strong></span></a> on the Jackson's Blog.</p><p>You can fit the bars together without tools, but a mallet (or a hammer with a scrap of wood) and a measuring tape or stick can be helpful. The bars come with small wooden wedges, also called keys, which are used later, after stretching, to add a bit more tension at the corners before you start painting. You can learn more about the canvas wedges that come with stretcher bars in this <a href="https://www.jacksonsart.com/blog/2018/09/12/how-to-use-canvas-wedges-that-come-with-a-canvas-or-stretcher-bars/" target="_blank"><span style="text-decoration: underline;"><strong>Jackson’s Blog post.</strong></span></a></p><p>Each bar has a slot at the end so the corners fit together at a right angle, creating strong, stable joints. When assembling, make sure the beveled edge of the bars faces inward, forming the inside edge of your canvas frame. Once all the corners are slotted together and any center bar is inserted, use a mallet to tap everything fully into place.</p><p>For step-by-step guidance on how to stretch canvas, watch <a href="https://www.jacksonsart.com/blog/2024/11/27/a-guide-to-stretching-canvas/" target="_blank"><span style="text-decoration: underline;"><strong>A Guide to Stretching Canvas</strong></span></a> on the Jackson's Blog.</p>
