SAFETY & WARRANTY INFORMATION

Meadow Burke guarantees its products, as shipped from the factory and when the above factors are taken into account. These products are intended for use

by qualied and experienced workmen. Even slight misuse, misapplication or lack of supervision and inspection can contribute to serious accidents. Unusual

applications beyond the scope of Meadow Burke bulletins, brochures, catalogs or drawings should be carefully eld-tested before general product use.

CHANGES IN PRODUCT DESIGN

Meadow Burke reserves the right to change product designs, safe load ratings and product dimensions at any time without prior notice to users. Such changes

will be made only for product improvement or additional safety.

WORN WORKING PARTS

It is the user"s responsibility to continually inspect working hardware for wear, and to discard the parts when wear is noted. Do not straighten bent bolts, rather

discard and replace. Discard any bolts known to have been used at loads of 70% ultimate strength or more. Such bolts may have been stretched sufciently to

become brittle-hard.

DYNAMIC

All rated safe working loads and safety factors shown in this catalog are for static" loading conditions. If shock, dynamic, or impact forces are anticipated,

additional safety factors must be applied.

SHOP OR JOB SITE ARC WELDING

DO NOT WELD TO ANY WIRE PRODUCTS, unless in the opinion of a qualied engineer, such welding is in a non-critical area. Welding to wire products causes

embrittlement at the load point and greatly reduces the load carrying capacity. Tack welding of wire products can have the same effect. Since Meadow Burke is

not able to control eld conditions or eld workmanship, Meadow Burke DOES NOT GUARANTEE any of its products which have been altered in any way (including

eld welding or bending) after leaving the factory.

SAFE WORKING LOAD DIRECTION

All SWL"s for the hangers shown in this catalog are axial loads for which the hangers are rated. The hanger SWL is in the direction of the hanger coil rod.

Depending on the angle of the rod in a particular bracket conguration, the vertical load which can be supported by the bracket (bracket SWL)

may be less than the hanger SWL.

Vertical Load < Axial Load

Direction of Vertical Load

AVAILABLE FINISHES AND COATINGS

Unprotected steel sometimes referred to as black, basic or raw steel. It will corrode or rust when exposed to the elements.

HOT-DIPPED GALVANIZED -

ELECTRO-PLATED -

WARRANTY

Meadow Burke will refund the price of, or replace at its election, any product which it nds to be defective, provided the product has not been misused. Except

as stated above, Meadow Burke assumes no liability for delay caused by defects, for loss of use, for any charges or expenses of any nature incurred without its

written consent. The foregoing statement covers the full extent of responsibility of Meadow Burke even though they may have been negligent.

The user of Meadow Burke Products must evaluate the product application, determine the appropriate safe working load and control and eld conditions to

prevent application of loads in excess of the safe load. www.MeadowBurke.com
