Top Suspended Unit for Use with Beam Attachment (Type B)

Type B is a spring support unit intended for attachment to overhead beams. Featuring a sturdy casing and various spring rates to accommodate different loads, it is suitable for vertical movements up to approximately 75mm. Its adaptability and durable construction make it a preferred choice for supporting piping in constrained environments.
