Developed over the course of a year, the Cadex ARCA Elite System (AES) delivers quick, smooth manipulations with a solid lockup. The AES clamp uses two stainless steel pins to lock the precision machined serrations down the center of the ARCA Rail for a system that will not move even under heavy stress such as sever recoil. The AES clamp can be used on competitors’ ARCA rails by removing the stainless steel locking pins, and adjustable tension ensures a perfect fit every time. The AES rail section on the other hand is precision machined from solid 6061-T6 aluminum to the tightest tolerances in the industry, and is built to the RRS standard ARCA rail dimensions to ensure all clamping systems work perfectly. Locking serrations are flush to the bottom so they will not interfere with clamping on a tripod, and provide a positive lock up and guaranteed not to slip under the recoil and loading.
