PURPOSE
The purpose of this policy is to provide information to familiarize Fresno Fire
Department (FFD and Department) members with the operational principals and
technical data necessary to properly operate the Ellis Shore Clamps. (See Figure 1.)
APPLICATION
The Ellis Shore Clamps allow a quick way to create an adjustable support system with
two pieces of nominal lumber.

PROCESS
1. Shoring Operation:
a. Get the proper length lumber to make a shore of the desired
height (5-foot, 6-foot or 7-foot lower shore member) and an
upper shore member long enough to achieve desired height,
plus enough length for 24 inches of overlap. (See Figure 2.)
b. Attach two Ellis clamps to the lower shore member 12 inches
apart and 6 inches from the top with four duplex nails through
the holes of each clamp.
The top clamp is to be a minimum of 6 inches from
the top of the lower post.
The bottom clamp is to be a minimum of 12 inches
from the top clamp.
The bottom end of the upper post is to be a minimum
of 6 inches below the bottom clamp. (See Figure 3.)

c. Slide the upper and lower shore members through the clamps
until the desired height is achieved.
d. Position the Ellis jack on the lower post with the handle
against the bottom of the upper post.
e. Pressurize the spot shore by lifting the Ellis jack handle. (See
Figure 4.)
f. After the desired height is obtained, the clamps on the upper
shore should be tapped down to seat them. (See Figure 5.)

g. A duplex nail should be driven into the upper shore member
above each of the two castings. This nail does not support
any load, but simply keeps the clamps from vibrating loose.
(See Figure 6.)
2. Lowering Ellis Shore:
a) Remove the upper duplex nails from the upper member only.
Loosen each clamp by tapping them up one at a time. The
Ellis shore will most likely lower slightly during this step. (See
Figure 7.)
b) For fast lowering, use a hammer to lift both clamps
simultaneously. (See Figure 8.)

Note: If done correctly, the upper member will drop very
quickly. Therefore, be careful to move your feet and
watch your head.
