Canvas Stretcher Bars

Each of our stretcher bars has a beveled edge so that the canvas will not show bar imprints. Slotted ends to fit seamlessly together. Constructed from high quality wood and available in four profiles. Stand out from the crowd and add a tray frame to stretched canvases. 

A stretched canvas can lose tension over time. Slotted corner joints allow the customer to tap wooden wedges, supplied with each pair of stretcher bars, into the corner, opening it up very slightly and re-tensioning the canvas.

All stretcher bars are supplied approximately 3mm shorter than listed sizes. Wooden wedges are included. No special tools are needed to assemble slotted Stretcher Bars. We recommend a soft faced hammer to tap the corners together.

Our stretcher bars are made to the highest specification and subject to careful quality control throughout production. Special attention to the shaping of the bar and corner joints guarantees that all of our bars fit neatly together and lie flat against the wall.

Each LION stretcher bar is purpose made, ready to assemble into any size. Choose 2 pairs of bars and slot them together. All have a beveled edge meaning that the stretched canvas will not show an imprint of the bars, and are designed for a seamless fit at the corners.

• No special tools needed for assembly, just tap together with a soft-faced hammer. Measure diagonals to check for squareness
• Wooden wedges supplied with every pair are tapped into corner slots to allow re-tensioning of canvas
• Slotted bars are supplied 3mm shorter than stated size to allow tensioning
• The edges are precision machined to a 2.25mm radius. This gives a crisp edge with minimal risk of cracking the ink film
• Careful machining of the slots means the bars slot together neatly and lie flat against the wall

How do I stretch a canvas?

Canvas stretcher pliers are essential to achieve a good amount of tension when stretching a canvas. Place the stretcher bar frame in the centre of a piece of canvas, ensuring there is enough canvas to wrap around to the back of the stretcher frame. Grip the canvas with the pliers and then use the ridge on the underside of the pliers to gain leverage over the edge of the stretcher frame and stretch around to the back of the frame. Always stretch canvas from the middle of the bars moving outwards, and insert staples opposite the ones you have just put in. A staple gun is the easiest way to apply staples to a stretcher bar frame.
