Quadra Brace is a 4-way Waler system which can create an open excavation as small as 7’6” square / rectangular and up to 24’ square / rectangular.
The system uses 3” steel cylinders and steel extensions to create a variety of sizes and configurations.
An extremely strong and versatile system for less stable soil conditions great for vaults, pump stations, tanks or any excavation needing a fully open area without cross bracing.
