'QUICK-SET' RETAINING ANGLES
BENEFITS:
• Factory fabricated by the manufacturer to suit
the individual fire damper.
• Dampers can ship directly to the job site
complete with all necessary installation sheet
metal hardware (saves on double handling at
contractor’s shop).
• Reduced cost when compared to conventional
retaining angles.
• Only two sets of angles to handle per damper
(rather than eight).
• Angles ship with individual damper - no
sorting or matching.
• Pre-drilled holes on 8
"
(203) centers to ensure
correct angle/sleeve attachment.
• Help ensure a correct installation as per U.L.
approved installation instructions.
The majority of installing contractors view fire damper installation as a costly time consuming and troublesome procedure.
Eight conventional angles must be custom fabricated for each damper either in a sheet metal shop or at the job site and
sized to suit each individual damper. Invariably, they are mislaid or lost and must be matched to each factory supplied
damper. The Nailor "Quick-Set" solution solves the majority of problems. They are pre-formed to fit each damper and
shipped with the individual damper units for ultimate convenience.
Option Code
QS1
provides a single set of angles for applications requiring angles on one side of the damper only.
Option Code
QS2
provides the complete kit of two sets of angles suitable for most applications that require angles on both
sides of the damper.
"Quick-Set" angles are supplied with correctly spaced pre-drilled screw-holes to ensure a quick, easy and accurate
installation for all Nailor fire dampers - no measuring required.
"Quick-Set" retaining angles when specified and supplied with Nailor integral sleeve fire dampers provide the "complete"
installation package. Simple, fast, convenient.
