The PROTO DIYBK is a replacement foam kit designed to fit inside tool cases for organized, secure tool storage. Made from chemical-resistant foam, this kit provides a custom-cuttable or pre-formed insert that keeps tools in place, reduces movement during transport, and protects tool surfaces from contact damage. The black and red color scheme assists with tool control and visual inventory management. At 2.25 pounds, the kit is lightweight enough to add minimal bulk to an existing case setup. Licensed tool storage professionals and technicians working in any trade discipline can use this insert to retrofit an existing case or build out a new storage solution.
The DIYBK foam kit is suited for both shop and field use across HVAC, plumbing, electrical, and general mechanical trades. It fits inside standard tool cases and is intended for technicians who need organized, damage-free transport of precision instruments, hand tools, or specialty trade equipment. The foam material family is plastic-based, offering durability alongside chemical resistance, making it appropriate for environments where tool surfaces may contact oils, solvents, or cleaning agents.
Designed for use with all PROTO tool storage cases and compatible as a general-purpose foam insert for standard tool case interiors requiring organized tool retention.
Installation requires no specialized tools. Remove existing foam or liner material from the case before fitting the new insert. Foam inserts can typically be trimmed with a sharp utility knife or box cutter to match custom tool outlines or case profiles. Ensure the case is empty and on a stable work surface before cutting or fitting the foam to prevent injury.
