If you have a 2188 and no rocktrap it means that you likely have a 60" feeder and you will require a 54.5" feeder AND a rocktrap assy as well. The 54.5" feeder+rocktrap equals the length of the 60" feeder. The 1400-1600 series had a 47" and 54.5" feeder option available and if a rocktrap was wanted it was "sandwiched" between the feeder and the rotor. This is not the situation with the 2100-2300 series, if you had no rocktrap you got a 60" feeder and cannot use this feeder with a rocktrap attachment. Feeders from 1600-2300 series will work. Goodluck.
