Palmer Safety 5-Point Full Body Harness

Palmer Safety Hammerhead Series 5-Point Full Body Harness with SRL Back Plate and Positioning Belt

The Palmer Safety H222101123 is a Hammerhead Series 5-point adjustment full body fall arrest harness engineered for construction professionals who require integrated work positioning, fall arrest, and SRL compatibility in a single harness system. Built with 1.73-inch polyester webbing rated to 5,000 lbs. breaking strength and alloy steel hardware in silver or golden yellow galvanized finish, this harness is designed for demanding jobsite conditions. It meets or exceeds ANSI Z359.11-2021 and A10.32-2012 standards, making it suitable for compliance-sensitive commercial and industrial applications. Available in sizes Small through 3XL to fit a wide range of workers.

Unlike standard fall arrest harnesses, the H222101123 combines a dorsal D-ring for fall arrest, an SRL back plate tunnel for a self-retracting lifeline, and a built-in construction positioning belt with side D-rings — eliminating the need for separate positioning accessories. The quick connect buckle chest closure with roller cam torso adjustment, tongue and buckle leg straps, padded back, and sewn-in fall indicators set this harness apart from basic alternatives in terms of comfort, versatility, and worksite readiness.

Key Features & Benefits

SRL Back Plate Tunnel

The integrated SRL back plate tunnel allows workers to attach a personal self-retracting lifeline directly to the harness back without additional hardware. This keeps the SRL positioned correctly along the dorsal spine, reducing snag risk and maintaining proper fall arrest geometry during a fall event.

Built-In Construction Positioning Belt with Side D-Rings

The heavy-duty back support and positioning pad includes a removable tool belt and work positioning side D-rings. This eliminates the need to wear a separate positioning belt over the harness, reducing weight, bulk, and fit complications — and keeps the worker properly centered for both fall arrest and positioning tasks.

Quick Connect Buckle (QCB) Chest with Roller Cam Torso

The quick connect chest buckle speeds up donning and doffing at the start and end of each work session, reducing time spent suiting up on multi-story or confined access jobsites. The roller cam torso adjustment ensures a secure, repeatable fit across different layers of clothing or PPE.

Tongue and Buckle Leg Straps

Tongue and buckle leg connections provide a positive, audible engagement that workers can verify by feel and sight. This leg strap design is preferred by experienced crews for its reliability and resistance to accidental release compared to pass-through buckles.

Padded Back with Sewn-In Fall Indicators

The padded back distributes load across the worker's torso during both positioning tasks and fall events, reducing fatigue over long shifts. Sewn-in fall indicators provide a clear visual signal after a fall has occurred, prompting immediate removal from service — a critical compliance feature under ANSI inspection requirements.

5-Point Adjustment System

Five independent adjustment points — shoulders, chest, waist/back, and legs — allow precise fitting for workers of varying body types across the full size range (SM–3XL). A properly fitted harness reduces both discomfort and the risk of the harness riding up or failing to engage correctly during a fall.

Breakaway Lanyard Keepers

Breakaway lanyard keepers route and secure connecting lanyards along the harness webbing, preventing trip hazards and keeping lanyards out of the work envelope. During a fall, breakaway design ensures lanyards release cleanly without adding dynamic load to the harness structure.

Common Applications

Structural Steel and Iron Work

The dorsal D-ring, SRL back plate, and positioning side D-rings make this harness well suited for ironworkers and structural steel crews who frequently transition between fall arrest and work positioning on beams, columns, and decking.

Commercial Roofing

Roofers working on low-slope and steep-slope commercial projects benefit from the integrated positioning belt, which allows hands-free positioning at ridge lines and roof edges while the dorsal D-ring remains available for fall arrest connection.

General Building Construction

Framing crews, concrete formwork workers, and general trades professionals working at elevation can use this harness as a single all-in-one solution for fall arrest compliance and positioning tasks without swapping equipment.

Tower and Telecommunications Work

The SRL back plate tunnel is specifically valuable for tower climbers who use self-retracting lifelines as primary fall protection during ascent and descent, keeping the SRL properly aligned and reducing dorsal hardware clutter.

Industrial Maintenance and Shutdowns

Maintenance technicians working on elevated platforms, catwalks, and process equipment can use the positioning side D-rings to free both hands for tool use while remaining fall-arrest protected through the dorsal connection.

Bridge and Infrastructure Construction

The heavy-duty webbing, alloy steel hardware, and ANSI Z359.11-2021 compliance make this harness appropriate for bridge construction and infrastructure projects subject to rigorous third-party safety audits.

Application Instructions

Pre-Use Inspection

1. Inspect all webbing for cuts, fraying, burns, chemical damage, or unusual wear before each use.
2. Inspect all metal hardware for deformation, corrosion, or gate malfunction.
3. Check sewn-in fall indicators — if activated, remove harness from service immediately.
4. Verify all buckles engage and disengage properly with audible/tactile confirmation.

Donning the Harness

1. Hold the harness by the dorsal D-ring and allow it to hang freely to confirm proper orientation.
2. Slip both arms through the shoulder straps.
3. Connect and adjust the chest quick connect buckle (QCB) across the sternum.
4. Connect tongue and buckle leg straps, ensuring no twists in the webbing.
5. Adjust all five points — shoulders, chest, torso roller cam, and both legs — for a snug, flat fit with no slack webs.
6. Secure the positioning belt at the hip; adjust side D-rings to desired position.

Connecting Fall Protection

1. Attach fall arrest lanyard or SRL to the dorsal D-ring only for fall arrest applications.
2. Thread SRL connecting hardware through the SRL back plate tunnel before connecting to the dorsal D-ring when using a personal SRL device.
3. Attach work positioning lanyard to side D-rings only — never use side D-rings as fall arrest anchor points.
4. Route connecting lanyards through breakaway lanyard keepers to minimize trip hazard.

Post-Use and Storage

1. Clean harness with mild soap and water; do not use solvents or abrasive cleaners.
2. Allow to air dry away from direct heat sources, UV, and open flame.
3. Store in a cool, dry location away from chemicals, sharp edges, and direct sunlight.
4. Remove from service immediately after any fall event regardless of visible damage.

Frequently Asked Questions

Q: Can the side D-rings on this harness be used for fall arrest?
A: No. The side D-rings are rated for work positioning only. Fall arrest connections must be made exclusively to the dorsal D-ring on the back of the harness.

Q: What self-retracting lifeline is compatible with the SRL back plate tunnel?
A: The harness is designed to work with the Palmer Safety SRL170 and similar personal SRL devices. Refer to the SRL170 Installation Quick Guide linked in the product documents for installation instructions.

Q: Does this harness need to be replaced after a fall?
A: Yes. Per ANSI Z359.11 and manufacturer requirements, any harness subjected to a fall arrest event must be immediately removed from service regardless of whether visible damage is present. The sewn-in fall indicators will also activate to provide a visual cue.

Q: How do I select the correct size for my workers?
A: Use the Palmer Safety Harness Sizing Chart linked in the product documents. The chart provides body measurement ranges corresponding to each size from Small through 3XL, accounting for chest, waist, and torso dimensions.

Q: Can the tool belt be removed from the positioning pad?
A: Yes. The tool belt integrated into the heavy-duty back support and positioning pad is removable, allowing workers to configure the harness with or without the tool belt depending on the task.

Q: What is the difference between the QCB chest buckle and a standard pass-through buckle?
A: A quick connect buckle (QCB) allows faster donning and doffing with a one-hand push-button release, versus a pass-through buckle which requires threading and double-backing. For high-frequency entry and exit applications, the QCB reduces time and reduces the risk of improperly threaded connections.
