RW-CAL Weld-On Commercial Anchor - CAL-OSHA Certified
The RW-CAL is the weld-on commercial anchorage device built for California work - certified to CAL-OSHA Title 8 Sections 1670, 3282, and 3291 on top of its federal OSHA and ANSI coverage. Designed for fall arrest, fall restraint, work positioning, and rescue operations, it pairs a 4 inch diameter post with a 5/8 inch U-rod connection point and welds directly to structural steel members.
Hot dip galvanized ASTM A36 rated steel withstands the toughest jobsites and weather, indoors or out, and the anchor is high strength, rugged, and reusable. Choose a 12 inch (RW12-CAL) or 18 inch (RW18-CAL) height, with a 5,000 lbf (22 kN) tensile strength and a 310 lb one-worker rating. Compatible with SRLs, shock-absorbing lanyards, and vertical and horizontal lifelines. Conforms to ANSI Z359.18 and A10.32 and aligns with OSHA 1926 and 1910.

Who Needs This Product
This product is a weld-on commercial anchorage device for structural steel - the anchor point of a fall protection system on California commercial roofs and structures. Contractors and building owners specify the RW-CAL because it carries the CAL-OSHA Title 8 certification (Sections 1670, 3282, and 3291) that plan checkers and safety managers in California look for. Each worker still needs a full body harness and a compatible connecting device attached to the U-rod.
Features
CAL-OSHA Title 8 certified
Sections 1670, 3282, and 3291 - the California personal fall protection and building maintenance anchorage requirements.
Two post heights
12 inch (RW12-CAL) or 18 inch (RW18-CAL) so the U-rod clears insulation and membrane build-ups.
Weld-on permanence
Welds to structural steel members - no fastener pattern, no penetrating hardware.
Hot dip galvanized
Full HDG finish over ASTM A36 rated steel for exterior or indoor service, extended durability.
Four-mode rated
Fall arrest, fall restraint, work positioning, and rescue operations from one anchorage device.
Broad connector compatibility
Works with SRLs, shock-absorbing lanyards, and vertical and horizontal lifelines.

Structure and weld carry the load. The anchor attachment structure must be verified for the required anchorage load by a qualified person, and the field weld must be performed by qualified personnel to the spec sheet requirements. One worker per anchor at 310 lbs maximum - calculate fall clearance before tying off. Standards conformance can depend on jurisdiction, application, and substrate - check the user manual and a qualified person before purchase and install.

Typical Applications
Installation Overview
Follow the manufacturer's manual. The sequence below is an overview only.
- Inspect. Check the post, U-rod, galvanizing, and label before installation.
- Verify structure. Have a qualified person confirm the steel member carries the required anchorage load.
- Position. Place the anchor at the engineered location in the roof access or fall protection plan.
- Weld. Perform the field weld to the spec sheet and engineer-approved procedure.
- Inspect the weld. Verify the completed weld and finish before the anchor enters service.
- Connect. Attach the connecting device to the U-rod and verify fall clearance before work begins.
Inspection and Retirement
Inspect before each use, with a documented competent-person inspection at least every 6 months. Pull the equipment from service for any of the conditions below.
- U-rod: bending, cracks, nicks, or wear at the connection point.
- Weld: cracks, undercut, corrosion, or any visible weld defect at the base.
- Post: deformation, dents, or damage to the 4 inch tube.
- Galvanizing: breached coating with active corrosion underneath.
- Markings: missing or illegible product label.
Retire the anchor immediately after any fall arrest event, any deformation or weld damage, or any condition where it cannot be verified as safe for service.
