The new Double Pull Down D3 Buckle is the smoothest operating lap belt in the industry with its patent-pending design and integrated adjusters. The D3 design has been further optimized by moving the shoulder belt loops closer together, making the shoulder belt V even tighter than in our previous design for the ultimate in safety and comfort. Our top-of-the-line Aluminum adjusters pair well with the integrated adjusters on the Latch and Link buckle to provide the smoothest and lightest adjusters in the market. The anti-sub belt link is the shortest design on the market which makes the buckle package smaller than any other for both comfort and safety. The D3 design connecting the shoulder and lap belts makes recreational use of the belts a simple and comfortable task increasing your and your passenger's safety. 5-point, bolt in
