Blue Clamp™ kits - designed for use in conjunction with lumber top course guides constructed by the builder. Blue Clamp™ kits and top course guides work with vertical bracing to align, control, and strengthen the wall, and to properly locate steel reinforcement. Typically, one (1) kit is required for every 8 LF of Blue Star walls. If the builder is constructing strongback caps for use with ReechCraft™ bracing, it may be possible to reduce the requirement to one (1) kit per 16 LF of wall. Blue Clamp™ kits are durable and reusable. Together with top course guides and eyebolts, Blue Clamp™ kits are required to ensure quality construction. Eyebolts are sold separately.
