Adir Blueprint Clamp 24 Inches - Blueprint Clips, Blueprint Binding Strips, Architectural Blueprint Binders for Blue Print Organizers, Poster, Maps & Construction Plan Holder (Pack of 6)

Work as they should.

These clamps are high quality. We hang them using the clip and it's important that the knobs are sturdy so when you tighten them they do not collapse twards the clamp creating less space for the hanger. These clamps are perfect, they hold up very well and we stuff a lot of pages in them! will be buying more soon

works great

very reasonably priced just as good as original

They hold the drawings but I should have gotten the next size up.

This purchase was driven by price. The Adir products are priced a bit lower than other similar brands, and that is reflected in the quality. These are not low-quality junk, but they are not top quality. Some of the end-caps arrived broken. This is not a big deal to me as the contractors pull the plans off the racks they tend to break and lose the caps anyway. The bind down tightly using a crescent wrench, and they hold the plans well enough. there are only 2 binders on the 36" plan stick, where some of my others have 3 binders. Pros - price, and they work well enough not to cause any major concern. Cons - they are "thinner quality" than some other brands but those come at a higher price. I have been using plan racks for 20 years during my career in construction management, and these are just fine. I would buy more of the same. ALSO - see my review on the wall mount rack to hang these on, there are some concerns there! Thanks. Adir Corp. Pivot Wall Rack with Hangers for Blueprints - Plans

The hangers are functioning as they should. Good so far but we have only had them about a month.

Got these for a hanging blueprint rack. They seem to be of good quality and the knobs torque down well to hold the pages tightly.
