ExoFit X300 Class ALP Wind Turbine, Seat Straps Beltless, DBI-SALA 3M Harness

ExoFit X300 Class ALP Wind Energy Harness DBI-SALA 3M

The ExoFit X300 Class ALP harness by 3M DBI-SALA is designed for workers at height requiring performance and protection. This harness features 6 lightweight aluminum D-rings: 1 dorsal D-ring with automatic stand-up positioning and anti-slip plate for fall arrest, 1 front D-ring for climbing and ladder ascent, 2 positioning D-rings mounted on the seat straps (comfortable seated suspension) and 2 lateral positioning D-rings at the hips (standing work positioning), 3M patented auto-locking buckles for quick and reliable donning, and an integrated RFID Connected Safety ID system enabling electronic inspection management. This harness is vest style, with vertical shoulder straps for easy donning and optimal comfort. Work positioning is achieved through the two lateral hip D-rings (for connecting a positioning lanyard, hands-free); this harness is not designed for prolonged seated suspension. It also features hip climb assist straps compatible with the 6160026 powered climb assist cable-grip for assisted climbing of wind-energy structures. Maximum capacity 420 lb (190 kg). Complies with CSA Z259.10-18. Made to order by 3M. Please allow approximately 1 month lead time.

Technical description : features and components

This Class ALP harness provides fall arrest, climbing, and positioning through 6 lightweight aluminum D-rings: 1 dorsal D-ring with automatic stand-up positioning and anti-slip plate (fall arrest), 1 front D-ring for climbing and ladder ascent, 2 positioning D-rings mounted on the seat straps (comfortable seated suspension) and 2 lateral positioning D-rings at the hips (standing work positioning). The seat straps, by their design, let the worker sit comfortably in suspension during prolonged work at height, while the lateral hip D-rings provide standing work positioning; the two systems differ by their anchor point and use. 3M patented auto-locking buckles click and lock automatically in a single motion, eliminating the risk of forgetting manual locking seen with conventional double-locking buckles. Each D-ring is made from anodized aluminum alloy, offering an excellent strength-to-weight ratio and superior corrosion resistance in wet or chemical environments. The RFID Connected Safety ID system, integrated into the harness body, allows safety managers to electronically record inspection dates and individual verification results. Five independent adjustment points (shoulders, chest, thighs, sub-pelvic) ensure an optimal fit and uniform force distribution during a fall arrest event.

Load capacity and certified safety standards

Maximum capacity of 420 lb (190 kg) including worker weight, clothing, and equipment. Complies with CSA Z259.10-18 (Safety Harnesses) in effect in Canada. Polyester webbing tensile strength: 6,000 lb (2,722 kg). This harness meets Canadian provincial and federal occupational health and safety regulations for work at height.

Materials : strength, durability and light weight

High-strength polyester webbing (6,000 lb / 2,722 kg), resistant to abrasion, moisture, and UV. D-rings made from anodized aluminum alloy, and quick-connect leg buckles of hybrid aluminum-alloy and zinc-plated-steel construction (light weight and strength at the highest-stress points): excellent strength-to-weight ratio, superior corrosion resistance versus alloy steel in wet or chemical environments, and reduced total harness weight to minimize fatigue. The RFID Connected Safety ID system is encapsulated in the harness body, resistant to impact, water, and dust. Padding zones use memory foam covered with breathable fabric for maximum comfort during long workdays at height. The quick-connect leg buckles use a hybrid aluminum-alloy and zinc-plated-steel construction, combining light weight and strength at the highest-stress points; this advanced material engineering, specific to 3M DBI-SALA harnesses, outperforms entry-level harnesses.

Application and recommended uses

The ExoFit X300 wind energy harness is developed for wind turbine maintenance technicians and renewable energy production workers. It withstands harsh weather conditions on wind energy sites: strong wind, marine humidity, cold. Aluminum alloy hardware generates no interference with turbine electronic equipment. Made to order by 3M. Please allow approximately 1 month lead time.

Inspection and service life : verification guide

Before each use, visually inspect the entire harness: webbing (wear, cuts, chemical or thermal burns, excessive UV exposure), hardware (deformation, corrosion, proper operation of 3M patented auto-locking buckles), stitching (fraying, tearing), and D-rings (deformation, cracks). A thorough inspection by a competent person must be performed every 6 months under normal use, or every 3 months under intensive use. Maximum service life is 5 years from first use or 10 years from date of manufacture. The harness must be immediately removed from service after any fall, even without apparent visible damage. Record each inspection using the integrated RFID Connected Safety ID system for complete traceability.

Maintenance and cleaning to extend service life

Clean the webbing with lukewarm water (max 37 degrees C / 98.6 degrees F) and a mild non-abrasive soap using a soft brush. Never use solvents, bleach, acids, or chlorinated products that degrade polyester fibres. Rinse thoroughly with clean water. Air dry away from direct heat and UV rays. Never place in a dryer. Clean the aluminum alloy hardware with a dry or slightly damp cloth. Lubricate auto-locking buckle pivots with light dry lubricant if needed. Store away from heat, humidity, and chemicals.

FAQ : frequently asked questions about this product

How does the RFID Connected Safety ID work?

A passive RFID chip is integrated into the harness at manufacture. With a compatible 3M Connected Safety reader, managers can read the unique identifier and record inspections. This system replaces paper tags and enables complete traceability in a centralized database.

How do I use the positioning D-rings?

Side D-rings connect to a positioning rope or movement restriction system. These rings are not designed for fall arrest: always use the dorsal D-ring for connection to the fall arrest device.

What is the sternal ring for?

The sternal ring, present on Class AL and APL harnesses, is designed for connection to climbing systems on vertical structures. It keeps the worker closer to the structure during climbing. It does not replace the dorsal D-ring for fall arrest.

Recommended complementary personal protective equipment

To complete your fall protection system, add a leading-edge SRL retractable (FPLR80302-12LE) or an energy-absorbing lanyard (FPL54000) as your fall arrest connection. Protect the head with a Peak T2 helmet with integrated chin strap (TA222), the eyes with safety glasses (YASF401BG) and hearing with earplugs (OA101). For the job, add suitable gloves (GS13SXGPU) and a flame-resistant garment (V7705).
