Jackson's : Museum : Alu-Pro : 45mm : Aluminium Stretcher Bar Pairs

ALU-PRO Aluminium Stretcher bars ensure maximum stability for your artwork. They are lightweight and easy to transport. ALU-PRO Stretcher bars are sustainable and eco-friendly.

The outer wood profile is to allow for easy back stapling of the canvas. The conservation benefits and archival properties of the aluminium mean that ALU-PRO canvases can easily be stored in damp studios where traditional painting surfaces would warp.

The Length of the Centre Bar
Centre bars are smaller than the stretcher bars because they fit inside the rectangle, whereas the stretcher bars are sized based on the outside of the rectangle they produce. We have already figured out the sizes that fit and they are labelled as the size needed for the rectangle, rather than the actual length of the bar. For example, a 50cm centre bar is not actually 50cm long itself, rather it is made to fit inside a 50cm stretcher bar.
