The ST-14 Snap Jack is an integral part of the Single Waler System and is used when forming walls over 8′ high to support a work platform. The steel one-piece unit quickly attaches to a Single Waler Bracket. Reference the installation sequence below. The Snap Jack has a built-in guardrail adapter to accept 2×4 guardrails. The lower support angle is provided with nail holes in order to nail the jack to the waler for added safety. Ths ST-14 Snap Jack works with both ST-10 Single Waler Bracket and ST-12 “A” Bracket.
Safe working load is 800 lbs. based on an approximate 4:1 safety factor. Do not, under any circumstances, place the Scaffold Jacks more than 8′ apart. Consult a Meadow Burke Service Center with questions concerning special load design applications.
