All springs have additional travel to solid equal to 50% of the rated deflection except SLFH-B2-450, which has 38% at rated capacity. Do not “jack up” equipment significantly during spring adjustment. Take two turns on each adjustment bolt working around the unit until springs are compressed just enough to remove blocks. INSTALLATION: Block up equipment to the Mason vibration isolation mount’s required free and operating height (see tables below), then make connections to the unit.

Use when equipment cannot be raised to the Mason vibration isolation mount’s free & operating height. Two inch deflection springs use the same holders as one inch springs. Mason SLFH two inch deflection spring mounts are for use on equipment located on upper level wide building spans, where more than one inch of deflection is needed to cancel the effect of the building span’s deflection. Start and stop as well as horizontal wind force will require the use of C, SLR or SSLFH Type mounts that have built-in horizontal limits. The Mason SLFH’s spring serves to isolate a broad range of disturbing vibration frequencies, while the rubber is a high frequency or noise break. Each Powder coated steel spring is in series with neoprene, providing excellent isolation efficiency.

Mason SLF one inch deflection spring mounts provide far greater vibration control than the lower deflection neoprene mounts. Braided Bronze Hose with Copper Sweat Ends Stainless Steel Flexible Connectors contribute to the solution of vibration, noise, expansion and offset motion problems in piping systems. For outdoor applications where wind loads may affect lateral stability, see Mason SLR or SLRH restrained spring mounts. Mason vibration isolation mounts are used to support equipment located on upper building levels where there are wide vibration sensitive spans. Mason SLF & SLFH Unhoused Spring Mounts provide the greatest deflection – up to 2″ to ensure excellent isolation.
