In a nutshell:
We offer you our Cam-Lock® hook system as a separate kit, just in case you have an old set of panniers that could use a little spiffing up! The Cam-Lock retro fit kit is available with two different track length 8” and 10” to perfectly match your needs. Our system is foolproof and lasts forever—why not use it on your other brand of panniers? The kit comes with everything except the tools to install it! It is fully adjustable and it's guaranteed for life.

The kit (pair) includes the following parts to retrofit 2 panniers, the kit (single) will retro fit a single pannier and comes with only half of the items listed below:

2 aluminum rails 8 or 10 in.
4 aluminum hooks with self locking cams and nylon inserts to protect the rack
2 carry handles
4 d-rings to attach optional shoulder strap
2 multifiber bungee
2 stainless steel wire hook
 

You can order the kit with 8 or 10 in. tracks depending on the size of your panniers.
