Custom Aluminum and Wood Stretcher Bars. Best existing product on the market. Fool Proof!
Since I deal with the serious painters directly, I can state that all large wood bars are finished!. The wood is not properly dried and they all warp. In anything 40in.X54in. and larger Aluminum and Wood DOES NOT WARP !!!
All corners and cross bars expand and contract with a wrench. They cost about 20% more than all wood.
