The handles are made from Polypropylene, with TPR overlay for increased comfort and reduced fatigue. 5 x Parallel Slotted: 2.5 x 50mm, 3 x 75mm, 3.5 x 75mm and 4 x 100mm (x2). Increased torque can be applied by using another bar through the hole at the top of each handle.
Very impressed, like Stanley tools, had to replace my old set due to water damage, unable to rescue, too far gone.
Much better than older items, easy grip handles
