Suggested minimum cleat
height for various sized
materials and degrees
of incline
This chart assumes that material being conveyed
has a 30° natural angle of repose. For rounded
or free-flowing materials with a natural angle of
repose of less than 30°, use the cleat corresponding
to the next higher material size. (For example, if
your material is 4” high, with a natural angle of
repose of less than 30°, and your belt incline is 40°,
you would use a 3” cleat — that is, the cleat size
corresponding to 5” material.
Suggested cleat spacing
This chart assumes that material being conveyed
has a 20° dynamic angle of repose (30° natural
angle of repose) and that cleats are installed at a
right angle to the belt edge. For more free-flowing
material, use slightly closer cleat spacing.

General Cleat Information
Cleat patterns
When choosing cleat installation
patterns, you should give major
consideration to the type of return
support which is available or feasible.
Where conveyor pulley center
distances are 15 feet or less, it is often
possible to omit return rolls safely.
Where the curved or chevron pattern is used
with standard return rolls, cleats should be
arranged so that they provide a set of
continuous contacts between cleats
and rolls. On drives using pulleys
less than 6” in diameter, curved or
chevron patterns should not be used.
The ends of cleats mounted in a
curved pattern should be tapered
to lead smoothly onto return rolls.
