The B-LINE SYSTEM INC B3100-3PLN is a size 3 plain finish clevis hanger designed for supporting pipe runs in mechanical and plumbing installations. Manufactured by Eaton B-Line, this clevis hanger provides a reliable, load-bearing connection point between the pipe and the overhead structure. The plain finish suits standard indoor applications where corrosion resistance is not a primary concern. Licensed plumbers, pipefitters, and mechanical contractors use this style of hanger to maintain proper pipe alignment, control sag, and meet code-required support spacing on horizontal pipe runs.
The B3100-3PLN is suited for residential and commercial pipe support applications where a size 3 clevis hanger is specified. It is installed on threaded rod suspended from structural members, beam clamps, or concrete inserts to carry horizontal pipe at consistent elevation. This hanger is a common component in HVAC hydronic piping, domestic water distribution, and process piping layouts where standard plain-finish hardware meets the project specification.
Designed as an OEM-style replacement and standard-fit clevis hanger for size 3 pipe support applications in mechanical, plumbing, and HVAC piping systems.
Installation is typically performed by licensed plumbers or pipefitters following IPC or IFGC support spacing requirements for the pipe material and size involved. Shut off the piping system and relieve pressure before adjusting or repositioning existing hangers. Use properly sized threaded rod and rod couplings rated for the anticipated pipe load. Do not overtighten the hanger bolt, as this can deform the clevis and affect pipe alignment.
