Calculators and planners
Six tools that answer the questions a spec sheet leaves open. Each one runs entirely in your browser, keeps nothing, and prints the formula it used so you can check it or do it on paper.
Most tool storage decisions come down to arithmetic somebody skipped: whether the drawer load is inside the derated slide rating, whether the cabinet still lets you walk past it with a drawer open, how many foam layers come out, whether a crossover box leaves room for sheet goods. These do that arithmetic and explain where every factor came from.
Drawer Load and Slide Rating Calculator
Turn a drawer slide pair rating into a realistic working load, with service, load position and wear derating applied and the factors printed.
CalculatorTool Box Fit and Clearance Planner
Check whether a tool chest fits your bay before you buy. Accounts for drawer extension, the depth of a person standing at it, vehicle width and car door swing.
CalculatorKaizen Foam Layer Calculator
Work out how many foam layers to remove for a given tool, how much base to leave, whether the block fits your drawer, and how many sheets the job needs.
CalculatorTruck Bed Tool Box Fit Finder
Enter measured bed dimensions and get the crossover size class to shop, the style your rail height suits, and how much bed floor you keep.
CalculatorSteel Gauge to Thickness Converter
Convert sheet steel gauge to thickness in inches and millimeters, weight per square foot, and relative bending stiffness. Includes the full Manufacturers Standard Gauge table.
CalculatorStorage Cost per Liter Calculator
Normalize tool box pricing by volume: exterior dimensions to liters, a usable-volume factor, then a comparison against our modular box database.
How these are built
No accounts, no email gate, no server. Every calculator is a small piece of JavaScript that runs on your device, and the dimensions and prices you type never leave it. Where a calculator applies a judgment factor, such as a derating multiplier, the factor and its reason are printed with the result. The reasoning is documented in how we analyze.
