ETC is supplying a free Headlock with every Source Four sold in the UK until the end of August. Designed by Nigel Hollowell Howard of HH Solutions, the Headlock slips over the yoke of the Source Four preventing the securing bolt rotating independently from the lantern. It's a partial Health and Safety measure in that the operator/focuser requires only one wrench or spanner, as opposed to two to tighten the hook clamp.

The Headlock can save as many as 30 seconds for each lantern you lock off by requiring only one spanner for all - or one hour for 120 lanterns. By reducing the number of tools required it becomes easier to work with them on lanyards and makes focusing safer for anyone below. The Headlock won the ABTT Product of the Year Award in 2001 and has sold more than 4,500 to date.
