This is a pair of Machined Anodized Aluminum 1" Square Tube Clamps. We make these clamps to specifically mount our 6.5" speaker pods to any golf cart with 1" square tube roof supports (roof struts). These clamps can be used to mount other things such as storage boxes, ball buddies, club holders or just about anything that can be drilled. Each clamp measures 2" x 2" x 1" assembled. Please measure your cart to make sure you have 1" supports. Buyer will receive 2 clamps with stainless steel mounting hardware (shown in photos).
