Great to use on the anchors of your truck bed!
These are good quality and look nice. I use them in my truck bed to attach to the anchors for easier use when securing loads.

...CLICK...?
...I really like these biners and use them on re direct lanyards, they have a good knurl on the gate and close with authority...now the one exception...there is a sill below the gate pivot...I have on numerous occasions taken tension to feel and hear a distinct CLICK as it slides to the lower surface of the hoop...just feels a little un nerving as they're used on my hip rings and I can't always see that they're seated...maybe they're just checking on my pucker factor!
