Exact replacement spline for my existing sreens. Each screen is about nine feet square, this spline holds them tightly. Installed easily with help from some liquid soap to lubricate the spline. Delivery was prompt, Good value in the large 1,000 ft spool.

I was searching for a flat spline that would be compatible with heavy duty pet screen in a porch screening system track. The manufacturer of the track said it couldn't be done but this spline made installation very easy without compromising the strength of the result. I love this spline!
