Our LockDown fastener is designed specifically for under-floor
PEX applications. Its loose hold allows PEX to move
during expansion and contraction of the tubing. The LockDown
wont pop open like other similar clips you may have seen or
tried. Use LockDowns for attaching 3/8 or 1/2 PEX; do not
use it for 5/8 PEX as it will fit too tightly. Order five LockDowns
for 10 of PEX. Follow all Installation Guidelines carefully.
