Buying Guide

Match profile to application

Choose 2020 for light frames and 2040 or SBR20 for heavier loads or longer spans to ensure stiffness and repeatability

Check material and finish

Anodized aluminum extrusions and chrome-plated steel rods resist corrosion and slide wear better than untreated materials

Verify mounting and compatibility

Confirm slot type (V-slot vs T-slot) and hole spacing to match brackets, wheels, or linear blocks used in your build

Consider bundled components

Kits that include rails plus bearing blocks or multiple profiles simplify sourcing and often improve alignment accuracy

Pick length and quantity wisely

Buy slightly longer profiles or extra pieces for trimming and squaring; modular extrusion packs can reduce joins and improve rigidity
