Industrial 5C129 Floor Mount Vibration Insulator

Mason Industries 5C129 Floor Mount Vibration Isolator is a spring‑type, floor‑mount isolation device designed to reduce floor‑transmitted vibration from machinery that weighs about 230 to 310 lb. It features a top‑adjustment preload bolt to set the spring load, delivering 0.75 in to 1 in of deflection and offering greater travel than neoprene or rubber pad isolators for improved vibration reduction; the spring is yellow and the assembly ships with the spring included. With an overall footprint of 5-3/4 in deep by 4-1/2 in tall and 2-1/8 in wide, the unit uses 3/8 in mounting bolts and has a center‑to‑center hole spacing of 4-3/4 in, designed for mounting on concrete or wood floors; Mason notes the product is manufactured in Thailand. Suitable for floor‑mounted equipment in industrial or commercial settings where vibration control is critical to protect nearby structures and processes.
