Shepherd PDT self-braking series notes; Admin titles [S1][S2].
A compression self-braking caster locks when weight is applied (usually when someone sits) and rolls when the chair is empty.
A decompression model locks when the chair is empty and rolls when weight is applied. Use it when you want the empty chair to stay parked.
They fit chairs with a 7/16 x 7/8 in grip ring socket. Measure the stem diameter and length before ordering. They will not replace a threaded stem without a socket change.
