You've Got Four Wall Protection! Flex-Shield™ Trench Boxes Manufactured By Trench Shoring Company

Are all trench boxes created equal? Hardly.

Other manufacturers' trench boxes are built with straight sidewalls that bow in under pressure when they are in the ground, making them almost impossible to pull. Trench Shoring Company's unique flex-Shield trench boxes are the only ones with a mid-section camber, making the box inches wider in the middle. When Flex Shield is in the ground and under pressure, its sidewalls become straight. The result: ease of movement on those deep, tight, hard-pulling jobs. The Flex Shield actually feels self propelled as it flexes.

NARROW SIDEWALLS
Flex-Shields are constructed with the narrowest possible sidewalls, so less soil has to be excavated and there is less backfill and compaction.

LIGHTWEIGHT BUT STRONG
Flex-Shields are built to give the highest pounds per square foot (PSF) for use in the deepest trenches.

BLUNT EDGES FOR FLEXIBILITY
By eliminating the knife edge found on the bottom of many trench boxes, the Flex-Shield can be used in any configuration when stacked in deep trenches.

ENGINEERED TO WORK FOR YOU
Both standard and custom Flex-Shields are designed by a Registered Civil Engineer in conjunction with Trench Shoring Company specialists.
