เหล็กหล่อเหนียว Heavy Duty 
Cast from SG. Ductile iron

Average clamping force of 300-800 kg (600-1760 lbs). Guaranteed unbreakable malleable iron frame
with a fast action twin start rolled acme thread. The steel swivel shoe applies an even pressure, even
on angled surfaces, whilst the tommy bar will bend before the frame can become over-stressed.
