John Evans HM10187-7B Helical Wire Rope Isolator 1/4in Cable Shock Mount NOS
John Evans’ Sons HM10187-7B helical shock & vibration isolator — the stiffest, most compact size in the 3/16″-cable (7–12) series at 2.00 in tall and 2.28 in O.D. Uses a three-hole retaining bar (6X mounting holes total), which spreads load over a longer footprint and resists rocking.
