these W.E.P.s needed to have the outer most edge modified. the hinge side I cut on a 45 and radiused with a 3" spindle sander to allow the door to close. the latch side needed to be cut back 1/4 inch too. I made a little jig to drill everything consistently and had to cut back the nest boxes a bit. weight difference with or without was negligible.
The overall fit was not perfect. I tried to have the top of the arch flush with the aluminum doors but the outer edges still had little bit of the aluminum door arches visible. I mounted these from the inside using 1/8 x 1/2 aluminum pop rivets
Thanks,
Bill
