This easy to install top is constructed of durable 25 oz pinpoint Black Diamond Sailcloth fabric or exclusive 3-layer 30 oz MasterTwill fabric with reinforced straps and a heavy-duty front header rubber seal to provide great weather protection. Each Bimini Plus attaches to your vehicle without the use of any extra components. Attaching with durable vinyl straps with reinforced buckles and to factory mounting points on the roll bar, this top goes on and off like a breeze. The front portion of the top attaches between the Rollbar and windshield providing a tight, wrinkle-free fit. MasterTop incorporates a heavy-duty rubber seal under the front windshield on their JL & Gladiator Bimini Tops/Bimini Top Plus to help prevent water and debris from entering the cab during heavy rain showers. Though this top is not waterproof, it will protect you and your passengers from sudden showers while driving and of course from the sun's harmful rays. Combine this top with a MasterTop Wind Stopper and Tonneau summer combo and you have a great summer top! Important Notes: Water can enter the cab in-between the doors and the roll bar as well as possible leakage around the front rubber seal near the windshield.
