3. Push pin tight against edge of hole along vertical center
line. Measure dimension between pin and hole (View B).
If dimensions A and B are not identical, hole is
elongated. Remove strap from service.
If two dimensions are identical, but greater than 0.030
in (0,8 mm), contact factory Service Department.
Storing Straps
Straps should be stored in a protected area. If stored in open,
a protective covering is recommended, especially in a
corrosive environment (chemicals, salt water spray, etc.).
Inspect straps in storage for corrosion monthly. If necessary,
sandblast to remove corrosion and repaint to maintain a
continuous protective surface. If corrosion is not removed,
strap will have to be removed from service because
reduction in thickness will exceed the maximum allowed.
A full periodic inspection is required for straps returned to
service from storage.
Removing Straps from Service
Straps removed from service should be clearly marked to
prevent accidental future use. Rendering the strap useless in
some way, such as cutting off an end, is recommended.
Inspection Checklist
A Strap Inspection Checklist is provided at the end of this
section. The checklist can be reproduced as needed.
Signed and dated copies of the Strap Inspection Checklist
must be kept on file at all times for each strap, as the
checklists may be required to verify warranty or product
liability claims.
If no damage is found or damage is within specification,
check the box (

)next to the item to indicate that its specific
condition was evaluated and found acceptable. If damage is
not within specification, indicate so in the box next to the item
(for example:
D to indicate damage).
