SLI Mechanical Heavy Weight Bars


Simon Liu, Inc. highly hand-crafted Mechanical Stretchers are made in solid basswood in Tongue & Groove L-Shape construction. It features Tite-Joint ® fastener and two guiding pins for the connecting miter and butt joint. Each perimeter bar comes with one set of fastener and two guiding pins, and each crossbar comes with two sets of fasteners and four guiding pins.

Keying is limited but the joints are stronger if keying is done properly. Wood shims are highly recommended for keying. After the proper tension is achieved, place wood shims between the hardware and guiding pins to hold the tension, then tighten the hardware to stabilize the joint.

Heavy Duty Profile:
1-1/2" thick x 3" bar width.  Deep profile provides approximately 3/4" clearance between the canvas and the perimeter's body.


Because of the overlap joints, crossbar configuration must be specified when ordering crossbars.  Configurations include: Single Crossbar, Top Crossbar, and Bottom Crossbar.
