Mako Series Full Body Harness H212101031

Mako Series Full Body Harness H212101031 — 5-Point Adjustment with Dorsal & Side D-Rings

The Palmer Safety Mako Series Full Body Harness (Model H212101031) is a professional-grade fall protection harness engineered for contractors and trades professionals working at height. Featuring a universal fit with 5-point adjustment, it accommodates a wide range of body types without requiring multiple SKUs on the jobsite. The harness is constructed with high-tenacity polyester webbing and alloy steel hardware, conforming to ANSI Z359.11-2021 and A10.32-2012 standards. Its two-tone blue-top, black-bottom design aids in quick visual orientation during donning and inspection.

Technical Specifications

The H212101031 distinguishes itself from basic harnesses through its combination of dorsal and side D-rings, enabling both vertical fall arrest and positioning applications from a single harness. The integrated fall indicators and two lanyard parking loops add inspection efficiency and worksite organization that single-D-ring, non-indicator harnesses cannot provide.

Key Features & Benefits

5-Point Adjustment System

Five independent adjustment points allow the harness to be precisely fitted across a wide range of body sizes, ensuring a secure and compliant fit for different workers on the same crew. Proper fit is critical to harness performance in a fall event, and the multi-point system reduces the risk of improper sizing.

Dorsal and Side (Hip) D-Rings

The dorsal D-ring supports standard fall arrest connections, while the side hip D-rings enable work positioning and restraint applications. Having both configurations on one harness reduces the need for workers to swap equipment between tasks.

Fall Indicators

Integrated fall indicators provide a clear visual signal if the harness has been subjected to fall arrest forces, allowing supervisors and workers to immediately identify a harness that must be removed from service. This eliminates guesswork during post-incident inspections and supports compliance with removal-after-fall protocols.

Two Lanyard Parking Loops

Dedicated lanyard parking loops keep unused lanyards secured to the harness body, preventing them from dangling and creating trip or snag hazards. This feature supports 100% tie-off workflows where a second lanyard must be managed while the first is connected.

Grommet (Tongue Buckle) Leg Straps

Grommet-style tongue buckle leg straps provide a positive, repeatable connection that is easy to verify visually and by feel. This buckle style is widely recognized by experienced workers, reducing donning errors in the field.

High-Tenacity Polyester Webbing — 5000 lb. Breaking Strength

The 1.73 in. wide polyester webbing is rated to a 5000 lb. breaking strength, providing a substantial safety margin above regulatory minimums. Polyester webbing resists UV degradation and moisture absorption better than nylon, supporting harness longevity in outdoor construction environments.

Galvanized Alloy Steel Hardware

All metal components are manufactured from alloy steel with a silver or golden yellow galvanized finish, providing corrosion resistance for use in outdoor and high-humidity jobsite conditions. Alloy steel construction delivers the strength-to-weight ratio required for reliable D-ring and buckle performance.

Common Applications

General Construction Fall Arrest

The dorsal D-ring connects to a self-retracting lifeline or shock-absorbing lanyard for fall arrest protection on structural steel, concrete, and framing work.

Work Positioning

The side hip D-rings allow the harness to be used with positioning lanyards, enabling workers to lean back hands-free while performing tasks on elevated structures or poles.

Roofing Operations

The universal fit and 5-point adjustment make this harness suitable for roofing crews where multiple workers share equipment across shifts.

100% Tie-Off Applications

The two lanyard parking loops support dual-lanyard 100% tie-off systems, allowing workers to park the trailing lanyard safely while advancing the lead connection.

Frequently Asked Questions

Q: What standards does the H212101031 harness conform to?
A: The harness meets or exceeds ANSI Z359.11-2021 and A10.32-2012.

Q: What size workers can this harness fit?
A: The H212101031 is a universal size harness with 5-point adjustment, designed to accommodate a wide range of body sizes without requiring separate small, medium, or large SKUs.

Q: How do I know if this harness has been involved in a fall?
A: The harness is equipped with integrated fall indicators that provide a visible signal when the harness has been subjected to fall arrest forces. Any harness that has activated its fall indicators must be removed from service immediately.

Q: Can this harness be used for both fall arrest and work positioning?
A: Yes. The dorsal D-ring is intended for fall arrest connections, while the side hip D-rings support work positioning and restraint applications.

Q: What type of leg strap closure does this harness use?
A: The leg straps use grommet-style tongue buckles for a secure, verifiable connection.
