Modular Support Blocks for Fluid Lines 
S
The problem: 
Fluid lines that run for any sizable distance frequently 
require some form of support at one or several inter-
mediate points. Such supports hold the lines firmly 
fixed to a wall, a ceiling, or the like, protecting them 
from structural damage that results from vibration and 
other stresses. One common support is a standard line 
block (see Figure 1) that is capable of holding several 
lines of identical diameter. This block is not suitable 
for parallel running lines that have different diameters. 
In that case each block must be custom made to 
accommodate the different line diameters.
The solution: 
A new, inexpensive, modular line block can support 
a number of fluid lines that have different diameters. 
These blocks are significantly more versatile and cheaper 
to manufacture than the standard line blocks. 
How it's done: 
As shown in Figure 2, the modular line block 
comprises a number of matched modular elements 
machined to accept fluid lines of different diameters. 
The modules can be arranged in a number of ways to 
support different fluid-line configurations. The top and 
bottom surfaces of each module are machined to accept 
a dovetail strip used for holding the modules together. 
The end modules, which also serve to fill gaps in the 
line block, have holes drilled through to accept the 
fastening screws.
