Guardian Fall Protection Cross Arm Strap 01630 X-ARM-48, 4 ft Pass-Thru

A Guardian fall protection cross arm strap in the pass-thru pattern — 01630 X-ARM-48

Every guardian fall protection cross arm strap solves the same problem — overhead steel, no anchor — but the 01630 X-ARM-48 solves it with the simplest hardware in the family: a sewn web loop. Wrap the beam, pass the strap through its own loop, pull the choke tight, and the D-ring end becomes your rated tie-off. Four feet of webbing, one ring to inspect, done.

As a cross arm strap anchor it covers the beams and joists that nail-on roof hardware never will; the pass-thru style is the pattern many crews learned first, and for cross arm strap fall protection rigging the wrap-edge-clearance rules below matter more than the choke style.

Key features

• Pass-thru sewn loop choke: webbing wraps, strap passes through itself
• D-ring end takes rated snap hooks and carabiners
• One metal part — less hardware to inspect than ring-choke patterns
• Guardian Fall Protection — SKU 01630, live Amazon pricing on the linked listing

Pros & cons

Specifications

What the X-ARM-48 is for

Mechanical, electrical, and maintenance trades working under decks and along beam lines — anywhere the overhead is structure rather than roof. It fills the pass-thru slot of the connectors collection, supplies the A of the ABC system in the fall protection equipment guide, and can serve as end anchorage for a horizontal lifeline span per the system manual. The worker’s side starts at the ranked harness guide and the loadout in the construction PPE checklist.

Building the system on this strap

Clip in a shock-absorbing lanyard from the lanyards collection (ranked in the lanyard guide) or an SRL from the SRL collection (ranked in the SRL guide) — a Saflok carabiner makes the D-ring connection clean, and every harness in the plan should carry trauma straps.

How the 01630 compares

Within Guardian, the 10787 Premium adds two feet and the dual-D-ring choke. Werner’s A-series strap undercuts on price at 3–4 ft, and KwikSafety’s Gibbon Grip runs 3 to 10 ft. Steel you cannot wrap takes the bolt-on FallTech 7414, and abrasive or hot wrap paths take the Guardian 10412 cable choker instead of webbing. The whole field lives in the fall protection collection.

Safety note: a strap anchor is one component of a personal fall arrest system — wrap it per Guardian’s instructions on structure a qualified person judges adequate, protect the webbing from sharp edges, and let OSHA 1926.502’s 5,000 lb-per-worker anchorage rule govern the rig in use. Anchor at or above the D-ring where geometry allows, run the clearance math, and retire every loaded component after an arrest.

Ordering FAQ

Is the Guardian 01630 X-ARM-48 in stock and ready to ship?
Yes — this listing is active and ships through Amazon. Open the linked listing for live price, availability, and delivery speed.

What does “pass-thru loop” mean on this strap?
One end of the strap is a sewn web loop: wrap the beam, pass the other end through that loop, and pull tight. The strap chokes the steel with webbing-on-webbing — no O-ring at the choke point.

What length is the X-ARM-48?
4 feet — the 48 in the name is inches. Enough wrap for common beams and joists while staying compact in a gang box.

Pass-thru loop or D-ring choke — which strap style is better?
Both rig in seconds. Ring chokes (like the Guardian 10787) slide a touch easier when setting; the pass-thru web loop has one less metal part to inspect. Crews standardize on whichever they rig correctly every time.

What structures suit this strap?
Overhead beams, joists, and cross members a wrap can encircle — the standard anchor for mechanical, electrical, and steel trades needing tie-off where no fixed anchor exists.

What connects to the strap?
A shock-absorbing lanyard or SRL through a rated self-locking snap hook or carabiner on the strap’s D-ring end. Anchor at or above your dorsal D-ring when geometry allows and run the clearance math first.

Is the 01630 OSHA compliant?
It serves the anchorage role in a fall arrest rig — OSHA 1926.502 requires 5,000 lb per attached worker or a qualified-person design, with the strap wrapped per Guardian’s instructions on structure that can take the load.

Can this strap sit against sharp steel?
Pad or avoid sharp and rough edges — cutting under load is webbing’s failure mode, and the pass-thru style puts webbing against the beam by design. Inspect the wrap path before rigging.

How many workers can tie off to one strap?
One per strap unless Guardian’s instructions state otherwise — the OSHA anchorage requirement applies per attached worker.

How do I inspect the X-ARM-48?
Before each use: webbing and the sewn loop free of cuts, fraying, burns, UV chalking, and chemical damage; stitching intact; hardware free of deformation or cracks. Retire after any fall arrest with the loaded system.

How does the 01630 differ from the Guardian 10787?
Length and choke style: the 01630 is 4 ft with a pass-thru web loop; the 10787 Premium is 6 ft with a large-and-small D-ring choke. Match strap length to the steel’s girth first, then pick the choke style your crew prefers.

Does this strap work as horizontal lifeline end anchorage?
Strap anchors are the usual end hardware for temporary HLL systems — but only per the lifeline system’s manual, which specifies the anchorage strength its arrest loads demand.

How do I reorder straps for a crew?
Reorder from this page — the listing and its linked Amazon ASIN stay constant, so adding a strap to every kit and gang box takes seconds.
