4.0 BRACKET SETS
For safe dependable service, the Extend-A-Gun MUST be securely mounted. To make the Extend-A-Gun as versatile as possible,
three mounting bracket kits are offered. Each kit has a different upper bracket. The lower bracket is the same in all three.

Task Force Tips strongly recommends that Extend-A-Gun be installed using the bracket sets sold by Task Force Tips that are
designed for this purpose. The Task Force Tips bracket sets are designed to fit the Extend-A-Gun outer tube very closely to prevent
distortion of the outer tube and to give it adequate support.
4.1 SELECTION OF STRUCTURAL SUPPORT ON FIRE TRUCKS
When the Extend-A-Gun is in the extended position, the nozzle reaction force can exceed 3000 lbs. These loads are transferred
directly to the mounting brackets and the structural members to which they are attached. It is crucial that the structural members
selected can withstand these forces.
4.2 BRACKET INSTALLATION
4.2.1 TUBE BRACKET INSTALLATION (EXTEND-A-GUN RC3 ONLY)
This kit contains a six inch square steel tube with two U-bolts to be used as the upper bracket, and a saddle bracket similar to a heavy
duty muffler clamp for the lower bracket. Both brackets must be used. This kit is designed for factory installation on new equipment.
The tube bracket is welded onto the truck tubular framework as shown on the Tube Bracket Welding Diagram. (see section 4.3.1.1)
The lower bracket, as shown in the Saddle Bracket Welding Diagram (see section 4.3.2.1), is welded to an additional support and
clamped as low at possible on the bottom of the Extend-A-Gun tube. Make sure the welds are capable of withstanding the forces
shown on the SIDE LOADS AT MOUNTING POINTS worksheet. (see section 5.0) The Extend-A-Gun may be installed in the brackets
after the truck is painted. Use thread locker supplied in the kit on U-bolt threads. Torque the nuts on the U-bolts used in the tube
(upper) to 15-17 lbf·ft. Torque the nuts on the U-bolts used in the saddle (lower) to 36-40 lbf·ft.
