Benefits of the Stage Depot Quad Spanner
What customers think
"When working at height, it's much easier to have one tool that handles all the common lighting hardware sizes. This is one of those tools that stays on your belt throughout the entire build."
"A great addition to our tools for the get-in of our latest production. We have a mix of 13mm, 17mm and 19mm heads on the set, so being able to keep only one tool with us has increased our efficiency and build time significantly."
"It's pretty! Sleek elegant design! Ratchets well! Does the job!"
Quad Spanner FAQs
- Q: What bolt sizes does the Stage Depot Quad Spanner fit?
- A: The spanner is a 4-way tool engineered to fit M8 (13mm), M10 (17mm), M12 (19mm) bolts, and standard 21mm scaffolding clamps or stage deck fittings.
- Q: Can this spanner be used with a safety cable at height?
- A: Yes. The Mk. 2 version features a 50% wider 10mm x 5mm tool lanyard slot designed specifically for quick attachment to the Stage Depot Event Rigging Tool Lanyard.
- Q: How does the Stage Depot Quad Spanner compare to a standard podger?
- A: Unlike a traditional single or dual-size podger, the Stage Depot Quad Spanner is a 4-in-1 multi-tool combining 13mm, 17mm, 19mm, and 21mm sockets into a single, compact 16mm slim profile profile. This eliminates the need to carry multiple heavy spanners or a pointed podger when working on standard theatre rigs or event structures.
- Q: What is the weight and length of the Stage Depot Quad Spanner Mk. 2?
- A: The Mk. 2 quad spanner weighs exactly 302g and features an ergonomic length engineered to provide maximum leverage on tight hook clamps and scaffolding couplers without overloading your rigging tool belt or tool pouch.
- Q: Is the ratchet mechanism reversible, and how much space does it need to turn?
- A: Yes, the tool features a smooth, reversible ratchet mechanism with a 24/22 tooth design. It requires an exceptionally tight 15° to 17° ratchet movement to turn bolts, making it the ideal stage rigging hand tool for tight spaces, over-stage grids, and dense lighting bars.
- Q: Can this tool be used on metric stage deck and truss bolts?
- A: Absolutely. The four socket sizes perfectly map to standard entertainment industry hardware: 13mm for M8 bolts, 17mm for M10 hook clamps, 19mm for M12 truss bolts/nuts, and 21mm for standard scaffolding fittings and stage deck leg clamps.
