050-0117 Two Rotor Latch With Coaxial Trip

This two rotor latch is designed for medium to heavy-duty applications for on or off-highway compartments and access panels. It features a coaxial trip mechanism for applications where it is desirable to provide additional support to the trip lever with a single position latch.

Designed For

  • Door thicknesses of 1-7/8" or greater (47.6mm)
  • Door weights of 50-200 lbs. (23-91 kg)
  • Door seal pressures of 50-150 lbs. (23-68 kg) (suggested for best results)
  • Applications where it is desirable to provide additional support to the trip lever
  • Use with TriMark 070-0200 Striker Bolt

Available

  • In left or right hand configurations (right hand shown)
  • With (4) 1/4-20 UNC or M6 x 1 threaded axles or .286" (7.3mm) diameter "thru" axles
  • With trip lever options (please inquire)
  • With a torsion return spring 

Finish

  • Zinc plated, clear chromate steel components

Material

  • Internal latch components: Heat treated, smooth edge stamped steel
  • Case halves: High strength steel
  • Springs: Non-corrosive stainless steel

Installation

  • (4) 1/4-20 UNC grade 5 or M6 x 1 class 8.8 or better fasteners are required (not included)
  • Tighten to the fastener manufacturers' recommended torque value, however, do not exceed 120 in-lbs (13.3 N-m)
  • Fastener mounting holes diameter should not exceed .281" (7.1mm)

Internal Lubrication

  • Oven-cured dry lubricant is applied at factory on all critical moving parts

Striker Installation

  • Install striker bolt in door frame
  • Close door carefully and check for interference between head of striker bolt and latch components 
  • Add or remove shims under striker bolt washer as required (outside diameter of shim should be larger than outside diameter of striker bolt washer)
  • Adjust striker bolt vertically so door is not guided upward or downward while being closed
  • CHECK TO DETERMINE THAT BOTH SECONDARY AND PRIMARY LATCHING POSITIONS ARE USABLE
  • Door should be latched but not "closed" in secondary position with respect to adjacent surfaces in primary position
  • If both primary and secondary positions are not evident, readjust striker bolt
  • After installation, check door alignment and door seal pressures

Caution Single position rotary latches do not comply with FMVSS 206 (ECE R11) requirements.
