Carlisle ST1 Lock Arm 336736

The Carlisle ST1 is a spray foam gun that requires periodic maintenance to ensure optimal performance. One of the maintenance tasks is to replace the lock arm on the tool, which is a metal piece that secures the trigger lock knob in place. The lock arm has the part number 336736 and can be found on the back of the gun, near the handle. The lock arm can be purchased separately or as part of the ST1 complete o-ring kit, which contains all the necessary o-rings and side seals for the ST1 gun.
