QLK/SPL Thread for 36 mm CPT Tubes

By half of the 1990-ies CPT has become more-and-more a highly productive industry. Operators make up to 14 tests of 25 meter per 8-hour shift. Strain-injuries in wrists and elbows are becoming a real issue and the industry asks for a newly designed thread. This resulted in the Quick-Lock thread (also called Speed-Lock thread).

The main advantages are the number of turns required to lock / unlock (only 2.5 turns), the improved strength of the thread (over 40% stronger than the STANDARD thread) and the relative ease to clean it.
