## Frequently Asked Questions

### What size key clamp do I need?
Key clamp size matches tube outer diameter: Size A (27mm/26.9mm), Size B (34mm/33.7mm), Size C (42mm/42.4mm), Size D (48mm/48.3mm), Size E (60mm/60.3mm). Most handrails use Size B (34mm).

### What castor capacity do I need?
Calculate total load and divide by number of castors. Add 30% safety margin. For a 400kg trolley with 4 castors: 400 ÷ 4 × 1.3 = 130kg capacity per castor minimum.
