StackTech Two-Shelf System provides a convenient way to store stacktech tool boxes in the workshop or work trailer/van. The system includes two robust shelves, supported by sturdy metal brackets, and two 20" standard e-track rails that can be securely anchored to walls or other surfaces. The e-track system allows adjusting shelf heights by moving the shelves along the e-track rails, giving you the freedom to organise your space exactly the way you need it. Each shelf has a generous 22 kilos weight capacity and built-in tie-down points to securely anchor straps. Increase your efficiency and productivity by adding the StackTech Two-Shelf System to your garage or work trailer/van setup for convenient off-the-floor storage of stackTech tool boxes.
