HammerHead Trenchless’ QuickLok inversion drums have two drum sizes capable of holding up to 125 feet and 225 feet of 4-inch liner, respectively, and a single-lever lockdown that gives a positive seal and secure latch. Other features include extra viewing ports and a detachable spindle wheel that makes it easier to navigate tight areas. Once in place, the wheel may be reattached to either side of the drum, accommodating workspace limitations or the preference of the operator. 800-331-6653; www.hammerheadtrenchless.com.
