Ryder Umbrella Mount - designed and manufactured by Rubicon Ryder, 30+ year Tool & Die shop owner, this umbrella mount is a MUST! Whether you're shooting in the blistering sun or potential downpour - the umbrella will shade/provide cover for the contents of your FOUR GUN Rugged Gear gun cart. The mounts are made for the Sport Brella Super Brella 8' umbrellas (available here, too). The Sport Brella Super Brella's have a 3/4" pole. The umbrellas will need to be drilled out to accept the pin that comes with the mount. HINT! ALWAYS put the pin in the mount after you remove the umbrella! The umbrellas sold by BBS are ready to use with the mount.
