Greenlee d-pfm2251150 Hang Anchor for Wood 3/8 Inch

Product Description

The GREENLEE d-pfm2251150 is a vertically mounted hang anchor designed for wood substrates, used to suspend threaded rod in structural and mechanical overhead installations. The anchor accepts a 3/8 inch rod diameter and features an end-drilled design that threads directly into wood framing or structural lumber. A Type 17 point style allows the fastener to self-start without splitting the wood, while a 1/8 inch pre-drill diameter is recommended for pilot holes in harder wood species. Zinc plating provides corrosion resistance in typical indoor environments. This anchor is rated to an ultimate tensile load of 1,450 pounds in fir wood, making it suitable for rod hanger applications in commercial and residential mechanical, electrical, and plumbing systems.

This hang anchor is used in overhead rod support installations where threaded rod must be suspended from wood joists, beams, or blocking. Typical applications include supporting HVAC ductwork, conduit runs, pipe hangers, and mechanical equipment from wood-framed structure. It is appropriate for both residential and light commercial construction where wood framing is the primary overhead structural material. Vertical mount orientation is standard for this anchor style. Electricians, plumbers, HVAC installers, and general mechanical contractors regularly use this type of anchor during rough-in phases of construction.

Key Features

• End-drilled design for vertical installation into wood framing
• Type 17 point style allows self-starting entry into wood without splitting
• 1/8 inch recommended pre-drill diameter for harder lumber species
• Zinc plated per ASTM B633 for corrosion resistance in dry indoor environments
• Ultimate tensile load rated at 1,450 pounds in fir wood
• UL Listed and FM Approved for use in fire-rated and listed assembly applications

Compatibility

Designed for use with 3/8 inch threaded rod hanger systems installed into wood framing, including fir and comparable structural lumber, with a 2.5 inch minimum embedment depth.

Installation Notes

Installation is performed by electricians, plumbers, and mechanical contractors working in overhead wood-framed structures. Pilot drilling at 1/8 inch is recommended prior to driving the anchor, particularly in dense or dry lumber, to reduce splitting risk. Verify embedment depth of 2.5 inches is achievable in the available framing member before installation. Follow applicable IBC, IFGC, or NEC support spacing requirements for the system being hung.
