I thought this was such a wonderful idea I ordered this for myself. It attaches to the breast beam of your 40" Gilmore loom and holds whatever you need to be close at hand. If you are using more than one weft yarn, this is where you second or third shuttle can sit until you need it. Or you can put your scissors, threading hook or sley hook here so they will be immediately available when you need to use them. It has been languishing up in the loft and needs to go help the next weaver in line. That could be you!
This trap is sized for a 40" wide Gilmore. The clamps at the end fit beautifully on my 44" Schacht Standard floor loom but the breast beam is too long.
