John Evans HM10187-3B Helical Wire Rope Isolator 3/16in Cable Shock Mount NOS
John Evans’ Sons HM10187-3B helical shock & vibration isolator — a small, stiff mount from the compact end of the 3/16″-cable line at 1.4 in tall and 1.6 in O.D. Use it where the supported mass is heavy for a small envelope and holding position matters more than long shock stroke.
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.
