Yes. The 3M DBI-SALA X300 Construction Style Positioning Harness — part of 3M's ExoFit X300 comfort harness line — is purpose-built for construction and positioning work, with 3 connection points: a back (dorsal) D-ring for fall arrest plus hip D-rings for work positioning. It adds hip and leg padding to reduce fatigue during long shifts, lightweight aluminum hardware, and auto-locking quick-connect buckles. It meets ANSI Z359.11 and OSHA 1910.140/1926.502, supports up to 420 lb (190 kg), comes in sizes XS–3XL, and ships with free shipping from Industrial Safety Products.

The 3M DBI-SALA X300 Construction Style Positioning Harness meets or exceeds ANSI Z359.11 (the standard for full-body harnesses), OSHA 1910.140 (general industry), and OSHA 1926.502 (construction). It is rated to a 420 lb (190 kg) capacity and is intended for industrial and occupational use only.

The 3M DBI-SALA X300 Construction Style Positioning Harness has a weight capacity of 420 lb (190 kg), which includes the worker plus tools and equipment within the rated range. It is available in seven sizes — XS, Small, Medium, Large, XL, 2XL, and 3XL — so you can dial in a secure, comfortable fit.

The 3M DBI-SALA X300 has 3 connection points made of aluminum: one back (dorsal) D-ring and two hip D-rings. The back D-ring is the fall-arrest attachment — the point you connect your SRL or shock-absorbing lanyard to — and on the X300 it's a lightweight aluminum automatic stand-up dorsal D-ring with an anti-slide pad that keeps it positioned for quick, efficient connection. The hip D-rings are for work positioning only (used as a pair with a positioning lanyard) or restraint, and must never be used for fall arrest. This combination is what makes the X300 suited to both climbing and hands-free positioning tasks.

The 3M DBI-SALA X300 is built with 6,000 lb polyester webbing (that 6,000 lb figure is the webbing's strength rating, not the user capacity, which is 420 lb). Its hardware is lightweight aluminum, with aluminum D-rings and aluminum-alloy/zinc-plated-steel buckles. The comfort padding is a nylon/polyester hybrid with reflective 3M Scotchlite panels for added visibility.

Yes. The 3M DBI-SALA X300 is a comfort harness designed to reduce fatigue, with hip and leg padding, a nylon/polyester hybrid comfort layer, and a sub-pelvic strap plus body belt that spread the load and support positioning work. The lightweight aluminum hardware keeps the overall weight down, and reflective 3M Scotchlite panels add visibility — all aimed at all-day wear on the job site.

The 3M DBI-SALA X300 uses auto-locking quick-connect buckles at the chest and legs for fast, secure donning, plus a revolving torso buckle and locking torso adjustment to fine-tune fit. The quick-connect buckles click into place and lock automatically, making the harness quick to put on and take off while helping ensure it stays properly secured.

No. On the 3M DBI-SALA X300, the hip D-rings are for work positioning and restraint only — they are used as a pair with a positioning lanyard to hold you in place for hands-free work, and must never be used to arrest a fall. For fall arrest, always connect to the back (dorsal) D-ring. Using hip D-rings for fall arrest is unsafe and not permitted under ANSI/OSHA fall-protection practice.

Yes. The 3M DBI-SALA X300 is Connected Safety ID (CSID) equipped, meaning it has an integrated RFID tag. A safety manager can scan the harness with a compatible device to log inspections, track its service history, and manage fall-protection equipment records, which helps keep the gear compliant and inspection-ready.

For construction and positioning work, yes. The 3M DBI-SALA X300 goes beyond a basic fall-arrest harness with dedicated hip D-rings for positioning, comfort-focused hip and leg padding, lightweight aluminum hardware, and auto-locking quick-connect buckles for fast donning. It uses tough 6,000 lb polyester webbing, is rated to 420 lb (190 kg), and meets ANSI Z359.11. It costs more than a basic harness, but the added comfort, positioning capability, and premium hardware are built for daily, all-day use.

Yes. The 3M DBI-SALA X300 features reflective 3M Scotchlite panels built into the padding for improved visibility on the job site. The harness is gray, comes in sizes XS–3XL, and ships with free shipping from Industrial Safety Products. It is intended for industrial and occupational use only.
