1033-4G CRA-4 18 Inch 4-Way Anchor Post
The Super Anchor 1033-4G is a 18 inch CRA-4 4-way anchor post, the riser that anchors horizontal lifeline intersections when fitted with the No. 1054 4-Way Top Fixture, sold separately. The foam filled, hot dip galvanized 3.0 inch Schedule 80 riser stands on a 52-hole 16x16x3/8 inch base plate, and the anchor is third-party certified with a 5,000 lb ultimate strength.
What is included: the riser post with base plate only; the No. 1054 top fixture is not included. The bare riser tube accepts the No. 1054 4-Way Top Fixture, which is required and sold separately, secured with a 1/2 x 4-1/2 inch stainless attachment bolt and 3 set screws. The fixture accepts up to 4 HLL run attachments for T, 90 degree, 45 degree, and 4-way intersections, plus single person loop top tie-off. Because 4-way anchors serve horizontal lifelines, they must be bolted, field welded, or concrete embedded, never screw attached. Compliant with ANSI Z359.18-17 and OSHA 1926.502, with CSA Z259.15:22 conformity per the 01-2023 manual.
Who Needs This Product
The 1033-4G is for contractors and building owners running multiple CRA horizontal lifeline runs across one roof. Where two or more runs meet, a 4-way anchor post fitted with the 1054 fixture ties the intersection together so T, 90 degree, 45 degree, and full 4-way layouts rig from a single anchor, and attaching HLL A ends at the 4-way lets the turnbuckle adjustment and energy absorber tension be monitored from one location. The 18 inch riser steps up to heavy wall Schedule 80 pipe and clears thick insulation packages and deep ballast. Each connected run supports 2 workers in fall arrest or 4 workers in fall restraint at 310 lb per user including tools per the 02-2021 rigging manual, and intermediate anchors are spaced 20 to 30 ft on center.

The riser ships without a top. Add the No. 1054 fixture, sold separately in galvanized or stainless, to accept up to 4 HLL attachments and single person loop top tie-off.
Up to 4 HLL runs
The 4-way top rigs T, 90 degree, 45 degree, and 4-way intersections with turnbuckle B ends and A end couplers per the 02-2021 rigging manual.

The 1054 4-Way Top Fixture is required and sold separately. The 1033-4G riser ships without a top and cannot be used for fall protection until the fixture is installed with its 1/2 x 4-1/2 inch stainless attachment bolt, seal washers on both ends, and 3 set screws. Because 4-way anchors serve horizontal lifelines, they must be bolted, field welded, or concrete embedded, never screw attached, and the supporting structure must hold 5,000 lb or 2 times the intended load per OSHA 1910.140.

Typical Applications
Installation Overview
Full rigging procedures and fixture attachment figures are in the CRA HLL Rigging Manual linked below. The essentials:
- Confirm the attachment point supports 5,000 lb or 2 times the intended load, with locations specified by the project architect, engineer, or safety consultant.
- Bolt the base plate with certified 1/2 inch grade 8, grade 5, or 18-8 stainless bolts with matching lock nuts, field weld with an E70XX certified welder, or concrete embed in 2,500 PSI minimum concrete.
- Set the No. 1054 4-Way Top Fixture onto the riser, align the attachment bolt holes, and insert the 1/2 x 4-1/2 inch stainless bolt with seal washers on both ends.
- Tighten the 3 set screws evenly with a 3/16 inch hex wrench, then tighten the attachment bolt with 3/4 inch wrenches until the seal washers are firmly set against the riser wall; do not over tighten.
- Attach up to 4 HLL runs at the 4-way top, rigging each B end first and tensioning turnbuckles per the 02-2021 rigging manual.
- Inspect the completed intersection, clamps, and tension gauges before the system goes into service.
Inspection and Retirement
Inspect before installation and each use, with documented annual inspections. Remove the anchor from service when any of the following apply:
- The riser is bent or deformed.
- Weld cracks are present.
- Rust that does not clean up with cold zinc coating.
- Fasteners are missing; do not use until the installation is corrected.
- The PID label or vent hole plug is missing and cannot be replaced.
- The anchor was subjected to a free fall or the supporting structure is damaged.
Tag anchors removed from service to prevent further use until inspected by a qualified or competent person.
