What We Like
  • Strong neodymium base magnet sticks firm upside down on tractor frames and truck fenders.
  • Flexible silicone bowl collapses flat to 3/4-inch thickness for tool drawer storage.
  • Silicone surface wont scratch automotive paint or catch metal filings permanently.
Flaws But Not Dealbreakers
  • Silicone attracts fine shop dust; wipes clean easily with a rag though.
  • Do not place directly against sensitive electronic sensors or magnetos.

The Straight-Shooter Take

Losing a proprietary flange bolt in tall pasture grass or having small washers drop into an engine bay turns a twenty-minute tractor belt replacement into a half-day nightmare. Traditional stainless steel magnetic trays are bulky, dent easily, and scratch car paint. PR1ME's collapsible silicone trays stick like glue to any steel frame while offering soft, flexible compartments.

Fit, Finish & Mechanical Integrity

The base houses an encapsulated neodymium magnet with a protective rubberized footing that prevents scratching painted metal surfaces. The silicone sides pop up into a deep 2-inch bowl when you need to hold dozens of bolts, or collapse flat to slip into shallow tool chest drawers.

  • Scratch Protection: Encapsulated magnet base prevents scratching painted tractor hoods
  • Heat Resistance: Silicone material resists hot engine oil, coolant, and brake cleaner
  • Collapsible Profile: Folds down to under 0.8 inches for compact mobile storage

Real-World Durability Check

  1. Tractor Bush Hog Service: Stuck the tray upside down on the mower deck frame while replacing rotary cutter blades; held heavy 1-inch nuts without dropping.
  2. Fluid Exposure: Soaked in diesel and hydraulic fluid during a filter change; washed clean with soap and water with zero silicone degradation.
  3. Cold Weather Flexibility: Kept in unheated shop during freezing weather; silicone popped open smoothly without cracking.

Bottom Line: Keep or Pass?

At under seventeen dollars for a 3-pack, these are absolute essentials for anyone wrenching on trucks, tractors, or lawn equipment. Keep one in the truck and two in the shop.
