Saf-T-Cart 503-20 Welding Cylinder Cart with Steel Wheels

The Saf-T-Cart 503-20 carries an oxygen cylinder and a fuel-gas cylinder, held by a permaclamp, on 20 in steel wheels. Saf-T-Cart says the steel wheels keep the cart flat free no matter how much abuse it takes.

Pick the build:

• Standard (503-20): Saf-T-Cart lists cylinder capacity as 9-1/2 in and 12-1/2 in diameter.
• Propane (503-20P): widened for a 100 lb propane or 115 lb propylene cylinder (Saf-T-Cart's catalog).

No firewall: the oxygen and fuel-gas cylinders ride side by side. OSHA requires oxygen cylinders in storage to be kept 20 ft from fuel-gas cylinders or behind a noncombustible barrier at least 5 ft high with at least a half-hour fire-resistance rating (OSHA 1910.253(b)(4)(iii)), and cylinders left on a cart between jobs can count as storage: when a firewall cart is the right call. For that, Saf-T-Cart builds this frame with a firewall: the Saf-T-Cart 503-20FW Firewall Cylinder Cart.

Choosing between pneumatic tires and steel wheels: which wheels for your floor.
