The Cache and the Rails System explained

TOM BIHN Checkpoint Friendly Laptop Rails System

Wondering what’s up with the webbing “rails” and Gatekeeper Clips on the back of your new Cache?

They’re a design update that allows you to secure your Cache inside of some of our larger bags, turning them effectively into convenient and checkpoint friendly laptop bag solutions.

The following bags currently have the webbing loops that allow you to attach the Cache via the rails system: Synapse 25, Synapse 19, Smart Alec, Cadet, Founder’s Briefcase, Tri-Star and Brain Bag.

Here’s how it works: on the back (or bottom, depending how you look at it) of your Cache are two parallel “rails” of 1″ wide, lightweight nylon webbing which extend from the top to the bottom.

Included with your Cache are what we call “Gatekeeper Clips”. (If you ordered your Cache before we included Gatekeeper Clips with the Cache, it’s necessary to order a pair from our Parts page should you choose to secure the Cache inside one of our larger bags via the rails system.)

Here’s how to operate the Gatekeeper Clips:
Squeeze the black part of the Gatekeeper Rail Clip together and flip up the rectangular metal bar to unlock the clip. Slip the open clip through the ribbon on the back of the Cache and flip the metal bar shut over the top of the clip. Repeat for the other side. Repeat the same process of opening and closing the Gatekeeper Rail Clip to attach it to the Rail Loops in your bigger bag. Slip the Cache inside the bigger bag, and pull it back out: you’ll see that the Gatekeeper Rail Clips ride the rails of the Cache, allowing you to remove your laptop from your bigger bag entirely while it is still encased in the protective Cache.

    The gatekeeper rail clips don’t work in the maker bag, right? They seem to only work in bags that are tall enough to put your computer in the bag sideways.

      Correct. We didn’t add rail loops to the Maker’s Bag because a Cache in the Maker’s Bag would limit access to the back pocket, if that makes sense.

    Just got my Cache for the IPad Pro, fits perfect. It’s so cool how is works with my Synapse 25!

      Glad it works for you, Bryan!
