#734- Optimally Designed to Protect the PEX Stub-Out
The HOLDRITE

ProGuard
TM
#734 in-wall PEX stub-out solution provides a rigid installation while maintaining the optimal outside bend radius
range recommendation of 3.3” to 3.4”. It also locks the stub-out in the Z-axis to prevent unwanted front to back slippage, making this patent
pending design the ideal solution.

HOLDRITE
®
the Expert in PEX Stub-Out Supports
For over fteen years, HOLDRITE
®
has been the expert in pioneering and producing innovative PEXRITE
®
PEX stub-out support products
for plumbing contractors, mechanical engineers, and PEX manufacturers in the North American potable water system market.
As the industry leader in stub-out pipe supports, our engineering design team has seen our PEXRITE
®
technologies successfully installed
by contractors. Their unique requirements led us to a more thorough understanding of PEX tubing performance, dierences in regional
installation methodologies, extreme climate and temperature ranges, and the challenges of various plumbing applications.
At the forefront of the evolution of PEX in North America, HOLDRITE can listen, learn, and innovate within the plumbing ecosystem. With
this applied knowledge we continue to expand our reputation for "Converting Makeshift Methods into Engineered Solutions

Observation and Discussion: Ideal PEX Stub-Out Solution
Below is a commonly observed schematic of a PEX stub-out within a conned wall that demonstrates the risk of extreme bending of PEX,
the challenges of tting PEX within the wall, and the ideal solution for a PEX stub-out support.
Wall Clearance Analysis: PEX Stub-Out Support
(3.50")
Clearance
Drywall
End of 90º bend -
support clears back wall
Allowing for grip of
1/2" nominal tubing,
the support stays
within the thickness
of 1/2" or 5/8" drywall
Optimal radius:
3.30" - 3.40"
(approximate)
(Allow .150" - .175"
thickness for support bracket)
(PEX bend support)
Beginning of Bend – Located
within Drywall Space
Ideal Solution - Broadest PEX Bend that:
a) Fits within wall, including bend support
b) Remains ush with drywall surface
c) Retains nominal clearance at rear
of installation
d) Allows nominal clearance length
for gripping tubing at near right
angle exit from wall

Summary: Bend radius that is too small risks:
a) Kinking or attening of tubing at installation,
or due to movement of tubing in wall
b) Reduced ow rate
c) Increased turbulence noise
d) Loss of PEX tubing warranty
e) Weakening or damage to tubing
f) Need for repair, to replace kinked tubing
