NOTE!
The QRail Hidden End Clamp is NOT a bonding solution and
therefore cannot be used on single modules. It must always be
installed in conjunction with at least one Bonding Mid Clamp.
NOTE!
When working at steep pitches it may be advantageous to
utilize Universal End Clamps while setting the module line. The
Hidden End Clamp can be tightened once the line is set and the
Universal End Clamp removed.
