Red Sea DIY Screen Net Cover Kit question

[Pyrosteve]

Hello All,

This might be a dumb question. I'm trying to make two small 12"x8" custom net covers and looking at the RS 24"x 24" kit. Can someone tell me if the internal corners and external corners are interchangeable? The kit lists 6 ext and 2 int corners (I'm needing 8 ext.) What's the difference?
TIA

They are not. The difference is the channel for the spline. For a standard square using the external 90 the spline channel is on inside of 90. The internal 90 has the spline channel on outside of 90.

Ahhhh... makes sense. That means I'll need and a cut out kit along with additional hanger kit. Thank you!
