Wunderbars Canvas Bars 24"

Product Description

Wunderbars are an exciting new concept in canvas stretching where the stretcher bars do the stretching & keep constant tension after the stretch. A stretched canvas can be completed in minutes with little knowledge or technique. Perfect for any business that stretches canvas. Wunderbars slot together square. Made from high quality tulip wood, all Wunderbars constant tension stretcher bars are machined so that the spring block just slots right into the bar, this makes the bars automatically square when you put them together. With the Wunderbar there's no need for you to hammer the bars together or measure the squareness, as you would traditional stretcher bars, they just slots into place No specialised equipment needed. Because of the way the spring blocks work there is no need for any expensive or professional equipment to stretch the canvas. All you need is a decent stapler & your h&. So no need for highly trained or experienced people to stretch the canvas either!! You just staple the canvas as you would do a normal canvas, but, this time only using your hands to pull the canvas. You don't need to pull hard, just enough so you can staple the canvas to the frame in position. When the pins are pulled the bars do all the stretching work for you. Automatically Stretches the Canvas Remove all 4 pins & your canvas is stretched. Simple as that. Theres no pliers, machinery or skill involved. If you include the frame squaring along with the stretching, it only takes a few minutes to stretch an entire canvas...giving those big bits of machinery a run for their money! Remember, anyone can stretch a canvas with Wunderbars stretcher bars. The Canvas is ALWAYS under tension No matter where you hang it, in the heat or  the cold the canvas will always maintain its tension because of the spring block inside. So there's no more hammering wedges or keys or returns to your customers for sagging canvas. Its just constant tension & a professional finish to your stretched artwork.
