Description
Product Summary
The Mason Industries SLFH-A-45 is a genuine Mason unhoused spring mount made to set under floor-mounted HVAC equipment such as air handlers, pumps, fans and condensing units so the springs absorb running vibration before it reaches the slab. It is built with an open, free-standing steel spring on a ductile base with a built-in leveling bolt, so the installer can level the unit and set the load after it is in place.
The SLFH-A-45 carries a rated load of 45 lb with 1.60" of deflection at that load, and its spring rate is 28 lb/in. Its spring is color coded blue, so the size is easy to confirm on site.
Pick the size by the actual weight each mount or hanger will carry: divide the equipment's operating weight by the number of isolators and choose the rating that covers that load. If you are not sure which size you need, call us at 1.888.509.3391 and we will help you choose.
Key Features
- 1" rated deflection for effective vibration isolation
- Leveling and adjustment bolt for setting the equipment level
- Color-coded spring makes the load rating easy to identify on site
- Neoprene friction pad under the base helps block high-frequency noise
