The Build-A-Box Sheeting Guide Frame from Efficiency Production uses lightweight corrugated sheets of aluminum to shore closely around existing cross-trench utilities. The sheets can be installed by hand, and the guide frame panel integrates seamlessly into any configured system. The result is a safe, maintained trench or pit that allows workers to access existing utilities. It can be assembled in minutes to a wide variety of two-, three- or four-sided configurations. This flexibility enables work crews to make on-the-spot design changes to meet job requirements in conditions ranging from light to extreme. Most systems are easily transported in a pickup truck or trailer for quick application. It is also compatible with XLAP Aluminum Shields. 800-552-8800; www.efficiencyproduction.com.
