About Interlock Shelving

Stelterr’s interlock shelving is a strong commercial and industrial steel shelving system that requires no bolts and uses an interlocking clip. This vital feature saves up to 80% of assembly time compared to traditional bolted units, making it extremely economical. Shelves can be easily re-configured, re-arranged, and all component parts can be installed without dismantling. Interlock shelving is the only shelving that can be completely assembled in an upright position, eliminating the need for extra floor space for the process.
