The Gateway is a modular accessory. The chain you wear with your gateway is what holds cores in place. To change it out simply remove the chain from the gateway and tip it out. Slide your next core in through the top, run the chain back through and go about your day. All standard-sized cores fit in this model.

Precision milled of 303 stainless steel.
