Client Feedback

Since the early 1980s I have used many different heavy duty stretcher bars, from some that barely warrant the name, to others that are like finished furniture both in weight and engineering. I can’t remember how I found out about your company but I am glad I did.

The bars are made of wood that is not only absolutely straight and well measured, but are extremely strong for their low profile and light weight. Also, they take staples better than any other wood I have used, saving time and effort. I am putting together an exhibition of larger works, and your well-engineered stretcher bars are proving to be the wisest choice. Thank you!

- Tom Paquette,

Van Witt Fine Art Conservation has ordered stretcher bars from Upper Canada Stretchers for the past 10 years. It has been a pleasure to have such a reliable and friendly service.

The quality of their workmanship, reasonable price, with the fast turnaround time has been a significant contribution to my painting conservation practice.
