OK if you are doing a pool screen most likely you're using flat spline.
Starting at the top, position screen and hold in place with a couple
pieces of tape. You need a spline tool to set the spline. Using the flat
end, not the grooved end, roll the screen gently into the channel. Take
the spline, rounded edge facing inwards into the channel and using a
screwdriver set the very end of the spline until it holds. Now place six
inches or so of spline into the channel at the lower edge leaving the
upper edge sticking out. Using the grooved end of spine tool now, roll
along spline exposed at upper edge until it seats into the channel. Be
careful to not cut the screen at the lower edge with tool. Repeat for
sides and then bottom last. Done!

I am getting ready to do this myself this weekend and have a quick question to clarify... You said that the rounded edge of the spline "facing inwards into the channel". So, put the rounded edge in first, got it... does it matter which way the rounded edge goes in? In other words, should the rounded edge face the inner edge of the screen or the outer edge (where trimming the excess will take place), or does it not matter?
