TECHNICAL DATA SHEET FOR
MODEL BEF- 5 BEAM END FITTINGS
The Caldwell Model BEF-5 is designed to use Schedule 40 ERW pipe (A53, Grade B, Schedule 40 Pipe)
as the central structural element between the end fittings. This structural material is readily available in
most locations. Caldwell Model BEF-5 requires a 5" nominal size Schedule 40 ERW pipe (A53, Grade B,
Schedule 40 Pipe) 5.563" OD, .258" Wall. The length of pipe used for this central structural component
must be straight within 1/2" end to end. This is required to prevent catastrophic failure of the pipe from
buckling due to an offset load on the pipe. If an inspection reveals that the pipe is damaged or bent, place
the unit out of service and report it to a designated person.
The ends must be cut cleanly and square with the centerline of the pipe. The Schedule 40 ERW pipe
(A53, Grade B, Schedule 40 Pipe) should not have any weld joint irregularities. The Schedule 40 ERW
pipe (A53, Grade B, Schedule 40 Pipe) used in this application does not need to have passed any pressure
testing.
Each end of the Schedule 40 ERW pipe (A53, Grade B, Schedule 40 Pipe) must have through hole drilled
as shown in Figure 1.
Figure 1.
The retaining bolt used to secure the Caldwell Model BEF-5 to the Schedule 40 ERW pipe
(A53, Grade B, Schedule 40 Pipe) must be a Grade 5 Hex Head Cap Screw 5/8-11 with a minimum
length of 8".
