Black fiberglass screen mesh, spline and a spline roller for pressing the spline into the frame groove. You supply a sharp cutting tool to trim the excess mesh.

Will it fit my porch door?

It is made for standard spline-groove screen frames on doors and windows. Check your frame's spline channel width and measure the opening before cutting.

Do I need special tools?

Only a sharp knife or scissors to trim the mesh. The roller in the kit seats the spline; a flat screwdriver helps lift the old spline out.

Is fiberglass better than aluminum mesh?

Fiberglass is rust-proof, cheaper to replace and easier to handle. Aluminum is stronger against tears and pets but dents and can corrode.

Can I use it for a pet door screen?

It will work, but fiberglass tears more easily under claws. Pet-resistant screen or aluminum holds up better for dogs and cats.

Remove the old spline, lay the new mesh over the frame, press the spline into the groove with the roller, then trim the excess mesh with a sharp knife.
