RECOMMENDED TOOLS FOR INSTALLATION OF INTERIOR STEEL SOFFITS, "JGI INTERLOCK™ CONCEALMENT SYSTEMS"
1. Aviation Shears/Snips may be used for cutting material in lighter gauges, such as our 24 Gauge material. A hand seamer or hand break also assists with custom fabrications. For cutting material to length, notching and cutting holes for sprinkler heads or other devices in heavier gauges, a plasma cutter is typically sufficient. Other useful tools include a die grinder, industrial grade jigsaw or hand held saber saw/metal cutter.
2. If more than a few dozen outlet holes are required, a carbide tipped hole saw is recommended. This tool expedites hole cutting and increases accuracy. When using this tool, you will also need a power drill with a higher RPM and at least a 1/2” chuck. Standard hole saw sizes for sprinkler head cut-outs are between 2” and 2 3/4”.
3. When encountering concrete structures a rotary hammer drill is essential for anchoring the cover clips. Typically, 3/16” x 8” length SDS carbide tipped hammer drill bits work well.
4. A high speed rotary drill, along with a 1/8” x 3” hardened steel bit, is required to drill rivet holes and in cut ends, cutting out sprinkler head holes, etc.
Additional suggested tools include:
-
A Chalk Line (For Determining Shield Clip Placement)
-
An 8” x 12” Steel Frame Square
-
A Combination Square (For Measuring Angles)
-
Medium-Size Rubber Mallet or Dead-Blow Type Hammer
-
2 – 3 Pry Bars/Nail Pullers (For Reaching Behind the Cover to Spread Shield Cover Clips and Other Fittings)
-
25’ Tape Measure
-
Cordless Drill for Anchoring Fasteners in Drywall and Drilling Pop Rivet Holes
-
Caulk Gun
-
Metal File (To Smooth Field Cut Edges)
Required Accessories:
-
Pop Rivets (1/8"Diameter x 1/4"Length) of Matching Material/Finish
-
Substrate Appropriate Anchors/Fasteners
-
Commercial Grade (Sonneborn® NP-1) or Institutional Grade (Sonneborn® Ultra) Sealant
-
Safety Glasses and Tool Belts
