Heavy Duty Stretcher Bars

John Annesley Company offers these heavy duty wood-keyed stretcher bar solutions in a variety of depths and configurations. All our stretcher bars are made from solid basswood which is a very light weight and straight grain hardwood with an almost neutral PH. What this means is that the stretchers are light, strong, guaranteed to be warp free, and are much less likely, than stretchers made from others woods, to react with paints in any negative fashion. Plus we provide a variety of edge treatments for our stretchers, allowing for a variety of framing options and painting techniques.

Much like a human face, the fabric on stretcher bars is effected by gravity and sags over time. Both linen and cotton duck show their sensitivity to heat and cold by expanding and contracting. This happens twice a day or more in most environments. Over time, the fabric fatigues and begins to loose its resiliency. Traditionally, the wooden keys hammered into the corners of the stretcher bars have been used to further expand the bars and take up the fabric slack. Wooden keys allow conservators the choice of direction in expanding the bars, but can take a painting out of square, or worse yet, damage the painting because of rough handling.

ur popular Heavy Duty Stretcher Bars are traditional wood-keyed stretcher bars, made to exacting tolerances. Corner joints are adjustable in each direction, with the supplied wooden keys. The braces are tenoned to fit into the mortise of the stretcher. They are recessed to back of the stretcher, and are expandable via the supplied wooden keys. The basswood used for these stretcher bars is totally free of knots and other physical defects.

We build to standard, fractional and metric sizes up to 40 feet!
We offer three types of stretcher bars:

Heavy Duty Stretcher Bars, (H3) 1-3/4" Thin Wraparound
The thin wraparound option is a 1-3/4" deep interlocking t-section added to the stretcher which provides added rigidity, as well as allowing fabric to be stretched over it and tacked in the back. This leaves the sides clean, eliminating the need for framing. The face edge of these stretcher bars has a beveled edge which raises fabric 5/8" off the stretcher bars and braces. Artists with a heavy touch will not hit the braces while working. The bracing is not only recessed from the face, but also recessed from the back by 3/8" to allow for the tacking of excess fabric.

Heavy Duty Stretcher Bars Kits

We offer these kits because it costs much less to ship the larger sizes when they are dissasembled. When we prepared the kits, first, all our bars are pre-assembled and each intersection is marked A to A and B to B, etc. The parts are then disassembled into a kit. The bars and bases will fit perfectly with one another as long as attention is paid to the markings.

Don't forget to order the fabric you need. We have a wide range of linens, cotton canvas and polyester for stretching.
