This expansion pack for the ULTICLIP UltiLink includes one lock-side mechanism and assorted mounting hardware. It can be bolted directly to grommets, to the included steel brackets, or to the laser-cut hook-and-loop strap. This kit will allow you to mount your pouch, knife, sidearm, magazine, what have you to a second place, or coupled with the UltiLink complete kit, give you two functional UltiLinks! Please note: This expansion pack alone does not include all requisite hardware for a functional UltiLink. This pack combined with the UltiLink Pinion Expansion Pack will give you a functional lock, or the UltiLink Complete Kit alone contains all the components of an UltiLink.
