Design and Installation Guide
• Shielding is not required at support points where the tubing is more than 3 inches away from any edge,
joist or plate and where unrestrained tubing has the freedom to move more than 3 inches away from a
possible point of penetration by a nail, screw or drill bit.
• When multiple runs of tubing are located between two studs or joists, panel striker plates PSP (6"
x 17") can be used as an alternative to individual striker plates. Plates are commonly used near the
mounting side of manifolds and branch.
