Our new customised heavy duty Sharp Edge Bar Bar features a 38 mm (1 inch) outer side but unlike our Round Edge bar's rounded top edge, the Profile 3 - Sharp Edge bar features a square edge for a clean, sharp edge after stretching.Profile 3 Bars are made from the best European re-forested timber, kiln dried and knot-free pine.The Profile 3 Sharp Edge Bar has been finger spliced - this is a method of bonding pieces of lumber together to form a very long, straight bar, that actually makes it a stronger support for your canvas.Each Sharp Edge Bar's profile has a 1/3" rise to prevent sagging and each bar is squared at the top edge for a clean, sharp edge after stretching.These heavy duty stretchers feature a strong tongue and groove design which means they just snap into place - no need for staples, pins or joining machines. Tape measure and mallet required for assembly. Note: We provide bracing slots on all sizes from 48" and above.  All products listed are usually of a large weight and size. Due to this fact, extra freight charges will be calculated upon check out.
