DESCRIPTION
A single leg of 1.125” polyester webbing with a D-ring on one end, and a snap hook for connection to the dorsal connector of a harness on the other. D- RING EXTENDER APPLICATION A. PURPOSE:

The D-ring extender is designed to make connecting to a Full Body Harness (FBH) Dorsal D-ring easier by extending this connection to where

it can be more easily reached. When attached to a full body harness, the
D -Ring Extender may be used as part of a personal fall arrest system ONLY if it is used in combination with other suitable fall arrest components.

WARNING: Unless otherwise indicated, users should not attach a shock absorbing lanyard or another connector to their dorsal D-ring when this device is in use. D-Ring Extenders are NOT designed for the purpose of extending the length of a shock absorbing lanyard.

KS7721 : D-Ring Extender with snap hook, 19” (48cm) length. This product is designed to allow users access to their back D-ring without removing their harness. By extending the D-ring, users can connect to an overhead SRL with ease (see Figure 1).
Instructions

B. USE LIMITATIONS:
Consider the following application limitations before using this equipment:

  1. CAPACITY: These D-ring extenders are designed for use by persons with a combined weight (clothing, tools, etc.) of no more than 310 lbs (140kg). Persons with muscular, skeletal, or other physical disorders should consult a physician before using. Pregnant women and minors must never use this equipment. Increasing age and diminished physical fitness may reduce a person’s ability to withstand shock loads during fall arrest or prolonged suspension. Consult a physician if there is any question about a user’s physical ability to safely use this product to arrest a fall or remain suspended.
  2. FREE FALL: For fall arrest applications, the length of the D-ring extension assembly must be taken into account when calculating free fall distances and fall clearance requirements. Refer to the other fall arrest system component instructions for free fall limitations.
  3. FALL CLEARANCE: Ensure that enough clearance exists in your fall path to prevent striking an object. The amount of clearance needed is dependent on the type of fall arrest system and how it is rigged.
  4. MAXIMUM ARRESTING FORCE: When used as part of a personal fall arrest system, the maximum arresting force must be limited to 1,800 lbs. or less.
  5. PHYSICAL AND ENVIRONMENTAL CONCERNS: Use of this equipment in areas with physical or environmental hazards may require additional precautions to reduce the possibility of injury to the user or damage to the equipment. Hazards may include, but are not limited to; heat, chemicals, corrosive environments, high voltage power lines, gases,  moving machinery, and sharp edges. Contact KwikSafety if you have any questions about using this equipment where physical or environmental hazards exists.

SYSTEMS REQUIREMENTS

A. COMPATIBILITY OF COMPONENTS: KwikSafety equipment is designed for use with KwikSafety approved components and subsystems only. Substitutions or replacements made with non-approved components or subsystems may jeopardize compatibility of equipment and may effect the safety and reliability of the complete system.

B. COMPATIBILITY OF CONNECTORS: Connectors, such as D-rings, snap hooks, and carabiners, must be rated at 5,000 lb. (22 kN) minimum breaking strength and comply with ANSI Z359.1-2016. KwikSafety connectors meet these requirements. Connecting hardware must be compatible in size, shape, and strength. Non-compatible connectors may accidentally disengage (“rollout”) or false engage. Always verify that the connecting snap hook or carabiner and the D-ring on the harness or anchorage connector is compatible. Some harness models have web loop connection points. Do not use snap hooks to connect to web loops unless the snap hook complies with ANSI Z359.1-2016. A selflocking carabiner may also be used to connect to a web loop. Ensure the carabiner cannot cross gate load (load against the gate rather than along the backbone of the carabiner). Connecting subsystems (self retracting lifeline, lanyard, rope grab and lifeline, cable grab, etc.) must be suitable for your application.

EXAMPLES OF INAPPROPRIATE CONNECTIONS:

A. To a D-ring to which another connector is attached (unless otherwise specified as being allowable)
B. In a manner that would result in a load on the gate.
C. In a false engagement, where features that protrude from the snap hook or carabiner catch on the anchor and seem to be fully engaged to the anchor point.
D. To each other.
E. Directly to webbing or rope lanyard or tie-back.
F. To any object shaped such that the snap hook or carabiner will not close and lock, or that could cause roll-out should a fall occur.

INSTALLATION PROCEDURE

A. CONNECTING THE D-RING EXTENDER TO THE FULL BODY HARNESS KS7721: Installation to the dorsal attachment element is made by opening the snap hook attached to the device, and attaching it to the dorsal D-ring of a Full Body Harness (FBH). INSPECTIONS

A. INSPECTION PROCEDURE

  1. Inspect the D-ring extension hardware (D-ring and snap hook). These items must not be damaged, broken, distorted, or have any sharp edges, burrs, cracks, worn parts, or corrosion. Ensure the snap hook closes completely and tightly.

  2. Inspect the webbing. The material must be free of frayed, cut, or broken fibers. Check for tears, abrasions, mold, burns, or discoloration. Inspect the stitching. Check for pulled or cut stitches.
    The webbing must be free of knots, excessive soiling, heavy paint buildup, and rust staining. Check for chemical or heat damage, indicated by brown, discolored, or brittle areas. Check for ultraviolet damage, indicated by discoloration and the presence of splinters or slivers on the webbing surface. All of these above factors are known to reduce the webbing strength. Damaged or questionable webbing should be replaced.

  3. Inspect all the labels. All labels must be present and fully legible.

  4. Inspect each system component or subsystem according to the associated manufacturer’s instructions.

  5. The D-ring Extender must be inspected by a Competent Person other than the user at least annually.

  6. Record the inspection date and results on the inspection log on the next page of this manual.
