Hot-forged 6061-T6 aluminum alloy, 8" tall Accepts 5/8" diameter oarlocks and pins A Pair of Oar Mounts includes two U-bolts with nuts and washers Single Oar Mounts do not come with hardware Weight of a single mount with hardware is 1.85 lbs. The NRS 8 Inch Oar Mounts offer tremendous strength and uncompromising stiffness for years of hard use. Made of hot-forged aluminum for a stronger, lighter, sleeker mount, these oar mounts put your oars up higher when you need more leg room on your raft or cataraft frame. Forging aligns the crystalline structure of the aluminum, creating a stronger oar mount while a tough nylon bushing allows the oarlock shank to rotate friction free. You can easily adjust the oar mount's height by rotating it on the side rail. Molded ridges on the gripping surface increase holding power on NRS's 1 5/8 inch OD frame pipe. A pair of oar mounts includes two U-bolts with nylon lock nuts and four washers and single mounts do not come with hardware.
