Knotted Climbing Rope

The improper use of rope MAY BE DANGEROUS

• Do not overload rope
• Avoid shock loading rope whenever possible
• Do not use rope in applications beyond the heat rating of the rope
• Be sure to use the correct size rope for the job
• Avoid any area around a liner length of loaded rope
• Keep rope away from all chemicals to prolong safe working life
• It is the user’s responsibility to use rope in a safe manner!!!!

IMPORTANT INFORMATION ON ROPE USE:

A rope's potential load capacity can vary greatly depending on its overall condition, how it's currently being used, and its exposure to the elements and other factors known to affect rope behavior. Because of this, and the possible risks to life and property involved, it is not realistic to make specific recommendations as to the exact loads any given rope can handle.

It is the user's responsibility to completely understand the safe use and operation of the rope being put into service for any specific or general task. The user needs to be aware of all environmental, load and any other variable factors that affect the safe use of rope. Failure to do so can cause severe personal injury and/or death as well as property and/or other environmental damage. The user of this rope assumes all such risks.

In addition, any safety training or skill training required for the safe use of rope in any capacity is the sole responsibility of the user of any rope.

Climbing ropes must be anchored to a smooth, round surface.  Failure to do so may result in a frayed/torn rope that can be extremely dangerous to the user.  If you are anchoring the rope to a non-round surface, we recommend the use of a sheath or some other form of rope protector.

ROPE STRENGTHS:

All rope has a rating referred to as a “tensile strength” or “average break strength” This number is the amount of weight that the rope should be able to hold in ideal conditions. This would be new rope, with no knots or plices, at room temperature. These break strength numbers are based on actual destructive break testing by the manufacturer or a certified third party testing facility over many cycles, and the average break strength is recorded and applied to the product.

Rope wear, knots, extreme hot or cold temperatures, chemicals, how the load is applied and many other factors can result in a break strength lower than the stated tensile strength.

Just because a rope has a stated or advertised break strength doesn’t mean it will safely hold something that weighs that amount!!! Refer to the safe WORKING LOAD of each specific rope for more information.

WORKING LOADS:

As a broad generalization, most working loads are anywhere from 1/10 to 1/4 of the average break strength of the rope. Any rope used in life support or personal fall protection applications must use the 1/10 ratio.

When in doubt, use a working load factor that affords a greater margin of safety, or move up to a larger diameter rope.

KNOTS & SPLICES:

Wherever possible, use splices constructed to safe specifications. A proper splice on rope can maintain 80 to 100% of the new rope average break strength. Trained personnel should perform all splicing. If knots are used on a rope be aware that they can reduce the rope strength by up to 50%. If knots are required, be sure to select the proper knot for the job.

STORAGE OF ROPE:

All natural fiber ropes must be stored in a clean dry place to maximize their safe working life. Synthetic ropes should also be stored long term in a cool, dry place. 3 strand ropes should be coiled or spooled up and braided products can be flaked or coiled in a bag or box if needed.

SPECIAL NOTE FOR EXERCISE CLIMBING ROPES:

Ropes popular for exercise climbing (like the manila or nylon 3 strand ropes) often are tied or secured to tree branches or interior steel beams to provide a vertical climbing rope. This attachment point must be inspected prior to each climb in order to ensure a safe and intact attachment point. Any knots or splices in this area can be subject to wear or environmental deterioration, so be sure to inspect these areas for any hazardous conditions that could create an unsafe attachment point.
