Griff Clips IV Packs of 22 with rings / metal clips OnTrax Systems Muslin Clips

Description

Griff Clips let you instantly have rope tie downs anywhere you might need them. It appears these were used for some sort of curtains / backgrounds in a photography studio so they can be a rod and then just switch out the different backgrounds.  Each item is a pack of 22, free shipping.
Instant grommet --no need to create holes or add grommets; just clip to your banner and attach a rope to the eyelet.
Info from the website:
Griff Clips: Our unique fastener for use in securing the edge of your material. Just pinch the edge of the material between the wedge-shaped sections and pull tight. Use the eyelet on the end to hold the item in place.
