Crouse-Hinds 529-S Malleable Iron Beam Clamp Insulator Support, 5/8-Inch Jaw

The Crouse-Hinds 529-S is a malleable iron beam clamp and insulator support engineered to secure electrical conduit, cable, and insulator hardware directly to structural steel beams and flanges. Featuring a 5/8-Inch jaw opening and a durable zinc plated finish, this beam clamp delivers a strong, corrosion-resistant mechanical connection for industrial and commercial electrical installations. Its rugged malleable iron body is built to withstand the demanding conditions of structural steel mounting applications while providing a reliable, code-compliant support point for electrical systems. Electricians and contractors rely on the 529-S when a fast, tool-friendly attachment to structural steel is needed without drilling, welding, or otherwise altering the beam, making it a practical solution for both new construction and retrofit electrical support work.

Key Features

  • Jaw Opening: 5/8-Inch jaw opening sized to fit standard structural beam flanges for a secure, direct mounting connection.
  • Durable Construction: Malleable iron body provides excellent mechanical strength and long-term durability for demanding support applications, standing up to the stresses of structural steel mounting over time.
  • Finish: Zinc plated finish helps resist corrosion and extends service life in industrial and commercial environments where humidity, dust, and temperature swings are common.
  • Beam Clamp / Insulator Support Design: Functions as both a beam clamp and insulator support, offering versatile mounting for conduit, cable, and insulator hardware to structural steel.
  • Reliable Hold: Clamp-style jaw design grips beam flanges tightly without the need for drilling or welding, simplifying installation and reducing labor time.
  • Structural Steel Compatibility: Designed to seat firmly on standard beam flanges, giving installers a dependable anchor point for downstream raceway and cable support hardware.

Crouse-Hinds 529-S – Frequently Asked Questions

1) What size beam flange does the Crouse-Hinds 529-S beam clamp fit?
The 529-S has a 5/8 inch jaw opening, so it seats on beam flange edges up to 5/8 inch thick. Thicker flanges, common on heavier structural members, need a clamp with a wider jaw. Measure the flange edge where you intend to clamp before ordering, not the web.
2) Can I attach conduit to a steel beam without drilling or welding?
Yes. The 529-S clamps onto the beam flange mechanically, so no drilling, welding, or other alteration of the structural steel is required. That is why it gets used on retrofit work where modifying the member is not permitted, as well as on new construction.
3) Does the 529-S beam clamp include the conduit strap or hanger rod?
No. The 529-S is the attachment point to the steel only. The downstream hardware, whether that is a hanger rod, strap, clamp back, or insulator, is ordered separately and must suit your raceway size. Plan the rod or strap at the same time so the hanger is complete on the first trip.
4) My beam flange is too thick for a 5/8-inch jaw - what beam clamp should I use instead?
If the flange exceeds the 5/8-inch jaw opening of the Crouse-Hinds 529-S, step up to a larger-capacity clamp such as the Thomas & Betts RC-2SC Steel City beam clamp, which is a 2-inch galvanized malleable iron clamp. Measure the flange thickness at the point of attachment before ordering, since a clamp that will not close fully on the flange will not develop its hold.
5) What is the difference between the Crouse-Hinds 529-S beam clamp and the Thomas & Betts RC-2SC Steel City beam clamp?
Both are malleable iron beam clamps for attaching electrical support hardware to structural steel flanges without drilling or welding. The Crouse-Hinds 529-S has a 5/8-inch jaw opening and a zinc plated finish, and doubles as an insulator support for conduit, cable, and insulator hardware. The Thomas & Betts RC-2SC is a 2-inch galvanized malleable iron clamp in the Steel City series. The practical split is flange capacity: the 529-S seats on a thinner flange at 5/8 inch, while the RC-2SC is sized at 2 inch.
6) Is the Crouse-Hinds 529-S suitable for a damp or humid industrial environment?
The body is malleable iron with a zinc plated finish, which resists corrosion in indoor industrial and commercial conditions with humidity, dust, and temperature swings. For continuously wet, exterior, or chemically aggressive locations, a hot dip galvanized or stainless support is the better call.
7) What is the difference between a beam clamp and an insulator support, and which is the 529-S?
It is both. The 529-S works as a beam clamp for anchoring conduit and cable support hardware to structural steel, and as an insulator support where insulator hardware has to be mounted off a beam. One part covers both mounting duties, which is handy when standardizing a stock list for an industrial plant.
8) Is a galvanized beam clamp a better choice than the zinc plated Crouse-Hinds 529-S for a damp or outdoor area?
The Crouse-Hinds 529-S uses a zinc plated finish on a malleable iron body, which is intended to resist corrosion in industrial and commercial interiors where humidity, dust, and temperature swings occur. The Thomas & Betts RC-2SC Steel City clamp is galvanized malleable iron. Galvanized coatings are generally applied heavier than electroplated zinc, so for washdown, exterior, or chronically wet locations many specifiers call out the galvanized clamp, while the zinc plated 529-S is the common pick for dry interior structural steel.
9) How do I order the Crouse-Hinds 529-S, and is there more than one version?
There is a single configuration: Crouse-Hinds model 529-S, manufacturer part number 529-S, malleable iron with zinc plating and a 5/8 inch jaw. No finish or size options to specify.
10) Why malleable iron rather than stamped steel for a beam clamp?
Malleable iron takes the clamping load and bending stress of a flange grip without cracking the way gray iron can, and it holds thread form for the clamp screw better than light stamped steel. On a support that carries raceway for the life of the building, that is the reason the 529-S body is specified in malleable iron.
