FallTech I-Beam Stanchion Clamp and Base, No Post
SteelGrip stanchion base with clamping set for I-beam mounted horizontal lifeline stanchions, sold without the post. Use it to mount a stanchion post to a new beam location or to replace a worn base and clamp set.
Three clamping sizes cover flange widths from 4 in up to 24 in: 630112CB (4 to 12 in), 630118CB (4 to 18 in), and 630124CB (4 to 24 in).

The Mounting Half of a SteelGrip Stanchion
Every SteelGrip I-beam stanchion is two assemblies: the vertical post and the base that clamps it to the beam. This product is the base and clamp set only, which lets you stage mounting points on multiple beams and move one post between them, or restore a stanchion whose base has taken a beating.
The base features plated steel construction with 7/8 in Grade 5 securing bolts, and the clamping rod features 1 in diameter plated steel construction with a wing nut and cotter pin for tool-free installation.
Key Features
Base and Clamp Only
Pairs with the SteelGrip stanchion post, sold separately, to complete an I-beam stanchion.
Three Flange Ranges
Order the clamp reach that matches your beams: 4 to 12 in, 4 to 18 in, or 4 to 24 in.
Grade 5 Fasteners
7/8 in and 1/2 in Grade 5 carbon steel fasteners secure the base to the beam flange.
Tool-Free Clamping
The 1 in plated steel clamping rod tightens with a wing nut and locks with a cotter pin.
Plated Steel Build
Plated carbon steel construction resists corrosion through years of structural steel work.
Replacement Ready
Direct replacement for the base and clamp set on existing SteelGrip stanchions.
The base is only as strong as its installation. Install per the FallTech manual on structural steel verified by a qualified person, torque the Grade 5 bolts to specification, and never load a horizontal lifeline system that has not been designed and approved as a complete system.
Compliance Standards
ANSI/ISEA 125-2014
Conformity declared by FallTech under declaration S0617003 covering the 630112CB, 630118CB, and 630124CB.
OSHA 1926.502
Horizontal lifeline systems must be designed, installed, and used under the supervision of a qualified person.
System Design Required
Anchorage strength requirements come from the complete HLL system design, not the clamp alone.
FallTech SteelGrip Series
Component of the SteelGrip clamping I-beam stanchion family; see the MHLL manual.
Typical Applications
How to Use
Follow the FallTech MHLL instruction manual. The sequence below is an overview only.
- Verify the steel. A qualified person confirms the beam and structure meet the HLL system design requirements.
- Clamp the base. Position the base on the flange, run the clamping rod through, and tighten the wing nut and Grade 5 bolts per the manual.
- Install the post. Set the SteelGrip post into the base, secure it, and rig the horizontal lifeline per the system design.
Inspection and Retirement
Inspect before each use following the MHLL manual. A competent person must inspect the system at least annually.
- Base plates: bends, cracks, and elongated bolt holes.
- Fasteners: Grade 5 bolts present, tight, and undamaged.
- Clamping rod: straight, threads clean, wing nut and cotter pin functional.
- Plating: corrosion that pits the steel rather than just staining it.
Retirement triggers: deformation, cracked welds, missing or damaged fasteners, or any loading by a fall. Remove the base from service and replace it.
