Product Details
Cortech and Master Lock™ have collaborated to create the Master Box, a robust and secure storage solution for inmate property. The Cortech Master Box™ features an integral tamper-resistant combination dial lock that includes a Master override key, effectively eliminating the need for traditional padlocks. Its "stack and nest" design allows for stacking property boxes with or without a lid without compromising the contents. The box is engineered with a radius design that incorporates rounded edges and corners for maximum impact dispersion and resistance. Vertical radial structural columns enhance the strength and impact resistance of the box, which is constructed from high-impact "no break" polypropylene. Additionally, it is flame retardant, passing CAL133 standards, with test results available upon request. The design includes an integral combination lock and hasp to securely attach the sliding lid to the box. Custom colors are available, and the product is backed by a 1-year warranty. The Master Box™ is manufactured to ISO quality standards in the USA.
