Extensions are used when you want to stack containers on top of each other. When purchasing an extension, keep in mind that your extension size correlates with the container you will have on the base of your setup. The extensions are made of hardened anodized aluminum with B7 all thread for maximum strength. (Note locking pack mounts are not recommended for use with extensions.)
New Anodized Aluminum.
Finally, you can stack multiple packs together! Use in conjunction with a pack mount (RX-PM, RX-PM-DLX, RX-PM-LOX).
IMPORTANT NOTICE ON SHIPPING:
*Many products will require the use of a direct shipping quote from one of our CSR agents due to new DIM weights and measure changes as of Jan 10th, 2018 from major carriers.
Packages greater than a square cubic foot are now required to use a “volumetric weight” based upon length, width, height of a package from most carriers which alters actual weights. Oversized / Unique shaped packages are most affected and may not apply to your specific purchase(s). However, IN ORDER to save you, the customer, shipping costs, associated fees, and to keep product costs down, we are taking action to give direct shipping quotes based upon delivery methods available. Your full name and email address, required in the checkout, is so we can offer you a shipping quote. Your item(s) will NOT ship without communication from our CSR agents. We apologize for any inconveniences.*
