What the Product Page Documents

Published July 16, 2026 · Last updated July 27, 2026

Two workers moving along a horizontal path — a roof ridge, a beam, a rooftop edge — need a continuous tie-off point that travels with them, and a horizontal lifeline kit is what makes that possible. The Guardian 04665 HTL is a 100 ft temporary rope lifeline with a built-in tensioner, rated for two-worker fall arrest or restraint, OSHA and ANSI compliant per Guardian's listing.

Shoppers searching a temporary horizontal lifeline for a job that needs rigging today rather than a permanent installation, or temporary horizontal lifeline systems and a temporary lifeline system more generally, land on the 04665.

Temporary horizontal access on roofs, beams, and similar structures where two workers need a continuous tie-off rather than fixed single-point anchors. It's ranked in our horizontal lifelines guide, and pairs with anchors from the anchor points collection, sized per our anchor requirements reference, plus a harness from the full body harness collection, ranked in our best safety harness guide, including Guardian's own Series 3 harness. It forms the connector-and-anchor link described in the fall protection equipment guide.

Where It Earns Its Slot

Where it earns its slot: Two workers moving along a horizontal path — a roof ridge, a beam, a rooftop edge — need a continuous tie-off point that travels with them, and a horizontal lifeline kit is what makes that possible. The Guardian 04665 HT. The sections below test that positioning against the documented configuration, not against wishful thinking.

Honest Limits

Honest limits: fall protection is system math. This component's rating assumes compatible companions, an anchorage that meets requirements, and enough clearance below the worker for the arrest to complete — run the fall-clearance calculation before trusting any height. Damage or deployment evidence ends its service on the spot.

Primary sources for this page

The wording behind this page sits in OSHA 29 CFR 1926.501, OSHA 29 CFR 1910.132, NIOSH Personal Protective Equipment.

Why trust this page?

Why trust this page? Every figure on it is taken from the published text of the standard or the manufacturer document named beside it, not from a secondary summary. WC Safety is an independent PPE review site: we hold no inventory and sell nothing directly, so there is no product we need this page to favour. Where sources disagree, the page says so and plans on the more conservative figure rather than picking one.

Methodology: how this page is maintained

Methodology. Figures are read from the primary source and re-checked whenever the underlying standard or a manufacturer document changes. No laboratory testing is performed for this page. Where a figure is not published, the page states that rather than estimating it, because a plausible invented number is more dangerous than an absent one.
