Worked as designed . Not used on an aircraft, but on a similar aluminum project. Great tool for riveting.

Used these to hold a backing plate on the inside of a carbon fiber tube. Worked like a dream so I could get the blind rivets installed tightly. Love that this thumbscrew version does not require a tool for use. (I have too many tools)

Well built and a must have in any tool box.

solid well made

Works great on keeping flanges pulled down for final drilling and riveting.

Long Reach Sheet Holder was the only tool I found that could hold 3/4 stack of aluminum doublers together for my Main Spar. Works great!

I purchased these in 3/32 size to tightly clamp the lower tail cone skins of an RV-14 build project. The arched ends of the clamping wires have a lower profile than standard cleco clamps. The lower profile caused the clamping wires to pull straight through dimpled #40 holes well before any meaningful clamping force could be applied, proving the clamps to be worthless for this application. I tried obtaining a return RMA online and found they are not returnable. I called customer service and asked where on the website I could find that they are not returnable before ordering the product and was told I probably could not. After I fussed a little about it, the rep did issue a return RMA. The rep was polite and considerate. I will be further investigating the companys return policy before ordering another product.
