Stryker T-top frames consist of three main components: two upright leg sections and one "hoop" top section. Each leg section has two solid billet aluminum clamps that fit on 2" diameter tubing. The top section has several welded 2" diameter crossbars that the legs mount to. When installing your t-top, you are going to slide them in or out until they are sitting right next to your center console unit on either side. Once in position, you can lock everything in for an extremely sturdy and stable frame. The image below helps illustrate how our t-tops are adjustable:
