Keeper Corp Ratchet Tie Down Strap Frequently Asked Questions
HOW TO CHOOSE A TIE-DOWN
Keeper recommends using a minimum of two (2) Tie-Downs to secure cargo and prevent load shift. Each Tie-Down should have a Working Load Limit equal to or greater than the weight of your cargo.
WORKING LOAD LIMIT
The maximum cargo weight a Tie-Down can safely handle and still accommodate unexpected forces caused by speed, road conditions or emergencies. The Industry Standard for Working Load Limit is 1/3 the Break-Strength of the Tie-Down assembly.
OPERATING INSTRUCTIONS
FOR RATCHET TIE-DOWNS
1. Place webbing over load and attach
hooks to solid anchor points.
2. Insert webbing through ratchet reel
and pull until ALL slack is out of
webbing. (See How It Works Tab)
3. Pump ratchet handle to make webbing
tight. Ratchet reel must have at least
two layers of webbing wound around it.
4. CAUTION, too many layers of webbing
will jam ratchet. If too much web is piling
on ratchet reel, start procedure over, first
removing ALL slack from webbing over
load.
5. After load is secured, move handle down
flat for transit. (See How It Works Tab)
6. To release, compress release bar and
open handle 180 degrees. (See How It Works Tab)
Keeper Hi-Test Webbing: The heart of a tie-down and tow strap is its webbing. The webbing design must be specific to the job. For example, the webbing used to lash a kayak to an automobile roof rack requires a different break strength, abrasion resistance, and weave pattern than a heavy duty ATV or motorcycle tie-down. Keeper is committed to providing high quality, long lasting, value driven products. Therefore, we design products with webbing that exceeds the demands of each specific application. Keeper introduced Hi-Test™ webbing to the tie-down market many years ago, using three layers of high tenacity yarn. The face, back and edge layers protect the webbing from abrasion and weather. The center, or warp yarns, provide the strength. All Keeper webbing meets appropriate abrasion capacity requirements so you and your customers are assured of longer lasting products.
| Componet Capacity |
The strength of each component of an assembly. e.g. Keeper P/N 04622, the ratchet begins to fail at 13,000 lbs., the hooks began to fail at 10,000 lbs., and the webbing breaks in excess of 12,000 lbs. |
| |
|
| |
|
| Rated Capacity |
Also known as "assembly capacity" or "break strength" is the minimum load a complete assembly can withstand before failure in a laboratory pull test when the product is NEW. e.g. Keeper P/N 04622 the failure occurs in excess 0f 10,000 lbs. |
| |
|
| |
|
| Working Load Limited |
The maximum weight of a load a tie-down should be subjected to during normal use. To assist the consumer in making the proper |
| |
tie-down choice for the job, Keeper, the Web Sling Association |
| |
and the Federal D.O.T. require the Working Load Limit to be |
| |
1/3 of the Rated Capacity. e.g. in Keeper P/N 04622 the working load limit is 3,333 lbs. |

DON'T BE FOOLED! |
| |
|
| The Webbing Makes a Difference |
Sewing Efficiency - As webbing is sewn it is weakened where it is pierced by the needle, reducing its strength by 10-20%. |
| |
|
| |
D.O.T. and Web Sling Association require each tie-down manufacturer to certify the Rated Capacity (Break Strength) and Working Load Limit of each product by attaching a tag or stencil to the product. |
| |
|
| |
To obtain the full 10,000 lbs. capacity for a 2" x 27' tie-down, "2 Stripe" (12,000 lbs. break strength) webbing must be used. "1 Stripe" webbing would only yield a capacity of 8,000 - 9,000 lbs. because of the sewing efficiency. |
