When the original Split Jaw company closed, the large scale community lost a valuable product. Split jaw rail clamps provide a superior track connection method that improves rail alignment and electrical connectivity. That's why we're happy to see Split Jaw Products taking up the banner, providing re-engineered split rail jaw clamps proudly made in the United States. SJP also offers track accessories and aluminum bridges, and has plans to produce custom and semi-custom large scale models through their SJP Custom Shop.
