Screws are not included with this part—they should still be attached to the loom side. The heddle bar support is attached with #10 x 1" Phillips flat head sheet metal screws.
How to Install
If necessary, detach the A-Frame Stand upright from the side of your Tapestry Loom (you can leave the adjuster bar in place) or remove the Tapestry Loom from the Trestle Stand.
Remove the screws holding the old heddle bar support.
Put the new heddle bar support in place, with the flat end at the back of the loom and the hole for the A-Frame Stand aligned with the hole in the loom side.
Attach the heddle bar support using the screws removed earlier.
Reinstall the A-Frame Stand or reinstall the loom on the Trestle Stand.
