1. Select the appropriate sling and rigging. Only use CornerMax® Sleeves and
Pads with synthetic slings.
DO NOT USE WITH WIRE ROPE OR CHAIN SLINGS. USE WITH OTHER TYPES OF
RIGGING IS PROHIBITED AND CAN LEAD TO FAILURE OF THE SLEEVE/PAD
AND/OR RIGGING.
• Refer to manuals and instructions of selected rigging for proper use.
2. Position the pads correctly on the load.
ENSURE PADS AND SLEEVES MAKE CONTACT WITH TWO LOAD EDGES.
3. CornerMax® Pads must be used in pairs.
4. CornerMax® Pads must be used at a 90˚ degree angle and make full contact
on both sides to create a separation between the edge of the load and the
sling.
USE
3

To prevent damage to the pad, sleeve, and/or sling do not expose to
chemicals and/or temperatures above 180°F/82°C.
USE (Continued)
Ensure sling is not too wide for the pad being used to avoid sling from
contacting edge. Refer to chart on page 8.
To prevent sling damage ensure all edges are protected. This can include
edges at the top of the object being lifted.
Materials that are hardened or have a Rockwell C hardness above 35 may
reduce eective protection for the CornerMax® Sleeve. Consult
Slingmax before using above this hardness.
4
5. CornerMax® Sleeves are versatile and can be used on any angled edge or
surface.
To ensure full contact do not use CornerMax® Pads on curved surfaces.
Use Cornermax Sleeve Instead.
Do not allow load edge to make contact with the CornerMax® Pad.

5
6.Apply the load carefully and slowly, ensuring the sling and pads and/or
sleeves are oriented correctly. You may need to perform this several
times to ensure the CornerMax® Pad and Sleeve are not being damaged.
Keep hands clear when the sling is being tightened.
To prevent cutting do not allow the sling, pads or sleeves to slide across
edges while under load.
BE CAREFUL WHILE USING HIGH STRETCH SLINGS, SUCH AS NYLON
OR POLYESTER, BECAUSE THEY ARE MORE SUSCEPTIBLE
TO CUTTING.
Stay clear of load at all times!
STOP THE LIFT IMMEDIATELY IF THE LOAD DOES NOT LIFT EVENLY,
THE PADS AND / OR SLEEVES SHIFT, OR ANY OTHER OBSERVED
FAILURE OF THE RIGGING IS DETECTED.
USE (Continued)

lbs by the width of the sling being used. For example, a 5” wide sling would have a
maximum working load of 125,000lbs.
