Identifying the right cylinder
Cylinders are identified by the outer tube of the jack, not by the bracket. Jacks of the same size can carry different brackets and still take the same cylinder. Measure the square dimension of the outer tube and its length: a 4 1/2" square tube 29" long is the 20" stroke CT.
Other strokes on the same 4 1/2" outer tube: 16" stroke is part 1466, outer tube 25" long; 30" stroke is part 3087, outer tube 39 1/2" long; 48" stroke is part 1161, outer tube 57" long.
Check your fittings before ordering
Older cylinders were built with NPTF fittings and current production uses SAE. On an SAE fitting there are no threads exposed between the cylinder body and the hex; on an NPTF fitting the threads are exposed. This cylinder has been supplied with both types over its life. If your jack has NPTF fittings, call EQ Systems at 800-846-9659 before ordering so the correct replacement fittings go out with the cylinder.
