No problems installing
Got this spline to install a "pet defense" screen on a patio door. The plastic screen is thicker but this spline worked perfectly.

Excellent spline , durable, thinner than average splines and cost way better than other providers
Handyman and myself happy with purchase as hardware store, big box stores don’t carry this size of spline .125inch x 100 ft for old type window screens ! Especially for installing pet screens which are thicker than most screens! Kudos to Amazon.ca for having this product in stock! I had this type of spline many years ago!

Tough, Flexible and Consistent
This is the right product for the job, have used two of these 100ft packs to replace all the screens on my house. Far better value than the smaller packs at the hardware store. It's tough yet flexible and always consistent, easily handling the fussy bits like working around the corners, the locating pegs and the puller where things can get a bit tight and fiddly. Choose the right size for your screen frames and this product will consistently create and hold the right tension during installation to make your new screen mesh look flawless.
