Simplex
Mechanical Trench Braces
Simplex Trench Braces provide efficient,
economical protection against cave-ins and costly redigging in
construction and utility maintenance. Braces extend by turning the lever
nut handle. The ball socket joints tilt for added safety on angular
mounting. Holes on each end facilitate mounting to wood members. |
|
|
Specifying Simplex Trench Braces |
Simplex trench braces are designed for use with
standard schedule 40 pipe. Screw end models SE-12, SE-16 and
butt end model BE-25 use 1 1/2" diameter pipe. Model SE-18
and butt end BE-35 use 2" diameter pipe. Pipe should be cut to length
based on the chart below and drawing in Fig. 1.. |
|
Dimensions assume the use of both screw &
butt ends together as an assembly |
