This 3 inch lift cylinder can have stroke limiters for cushioning and a 4.5 inch pipe. When folded, the total length is 8.75 inches from finger to toe. Extended is 11.75 inches from finger to toe. It's too long for what I needed it for, but it was a good price and service so I'll keep it anyway. The first one I ordered was a 4 inch device with the 10 inch pen retracted. If sizes are right, these guys are for you.
