For some applications, screwlinks are a better choice than Carabiners. When properly closed, they're safer than locking 'biners. Since they don't tend to unlock on their own, screwlinks are ideal any place you want a super secure connection (I.E. attaching a descender to your seat harness). They're also smaller, lighter and less expensive than carabiners. Half Moons are used to close seat harnesses because they can be loaded all along the curved side. Long MR's are also great for rigging. Short links are a good alternative to locking 'biners in ascending systems. All other MR Screwlinks available, please call.

Which 'biners? The array can be endless. To lessen the confusion, we've chosen four basic styles and a few major brands. We think that most folks will find a 'biners to suit their needs in this list. Don't feel that we're limiting your options though. GGG carries full lines of Kong-Bonati, Petzl, Omega-Pacific, and SMC carabiners. If you want something specific, please ask.

What 'biners to use? D-shaped carabiners should be loaded along the long axis, so only one thing should be clipped into each end. Ovals aren't as strong, but allow for attaching multiple items. Pear-shaped (HMS) 'biners are good for use with the Munter hitch for belaying or emergency rappelling. Non-locking 'biners are for cow's tails and rock climbing; straight gates are the standard, while bent gates open wider for easier clips.
Never close a seat harness with a locking carabiner. A half moon screw link, designed to be loaded in several directions at once, is much better suited for this use. If you have any questions about hardware use, call us!
