Door/speed brake cylinders, Eight Stroke Lengths to chose from

Used for years by quality minded modelers, the JMP Door Cylinder is now available in eight stroke lengths. These door cylinders are perfectly machined and carefully assembled with each one required to pass a “bubble tight” leak check.

 They are designed with a precision fixed orifice that stops the “snap action” and door slamming of other styles while eliminating the additional cost of separate restrictors. The piston rod has 4-40 thread for Quik-Link, Rocket City or ball link attach points.

Available in 1/2" increments from .5” of stroke length through 4” of stroke length.

Also, pictured below is the 1” stroke length cylinder with the custom machined cylinder pivot post for secure mounting. The pivot post fits every cylinder length.
