That might be a good option if you like the design. I was looking at that strainer for a Kent snare I'm trying to get back together. I just dont know if the mounting holes are 1 inch apart hole to hole, or center to center.
Actually, now that I think about it, that strainer might not be your best option if your snare shell is one of the thin 3 ply shells. If it is 5-9 plies, it would be fine, but if it's thin, the holes being so close together might put too much tension on the shell.
Other than finding another original strainer in better shape, I know of no direct replacements for the old 3 hole spacings. There might be one out there, I just dont know about it.
