JUMBO SOLID STEEL DUMBBELLS

6-YEAR WARRANTY against Loosening Weight Heads

6-YEAR WARRANTY against Structural Breakage

6-YEAR WARRANTY against Bent Handles

HANDLE OPTION: Hard Chromed Classic Knurling

AVAILABLE from 155 lbs to 200 lbs in 5 lb increments

Maximum value: Competitively priced, our innovative design technology results in an extended product lifespan yielding exceptional value.

Durability: A patented fastening technology between the heat-treated alloy steel handle(the strongest used in the industry) and the solid steel core(dumbbell weight head) makes Barbell Company solid urethane dumbbells maintenance-free against loosening up. High strength steel handles offer a 6 year warranty against structural breakage. 4140 heat treated alloy steel handles are used on dumbbells and heavier. (see detailed information below about dumbbell handle materials)

Function: Handle thickness is limited to 1-1/4” (32mm) to ensure a solid, secure and comfortable grip. High quality alloy steel is used to increase handle strength where other brands use an oversized diameter handle thickness around 1-3/8” (35mm) to compensate for their weaker regular carbon steel handle material.

Our heat-treated alloy steel dumbbell handles are machined with a greater number of points per square inch resulting in a comfortable knurling while maintaining performance and a sure grip similar to that used on high quality competition style Olympic bars.

King-Collar(patent pending) PROVIDES 3 TIMES MORE HOLDING POWER THAN A REGULAR COLLAR. It increases the holding surface by 3 times compared to most other brands' regular handles with smaller collars that "eat" into the plates or weight heads. King-Collar solves this problem.

Appearance: The durable black zinc finish is specially formulated for use in high impact environments and is unsurpassed in the industry for appearance and durability.

Suggested Usage: All Commercial Gyms & Weight Rooms

• 1018 & 1045 are regular carbon steel.
• 5140 & 4140 are alloy steel.
• 1018 steel can not be heat treated due to the low carbon contents in the material.
• Welding does not bond well between two different materials, such as carbon steel and stainless steel.
• Heat treated dumbbell handle will not improve the structural strength when welded with solid dumbbell head. The heat created from the welding process will anneal the material back to soft condition and cause the weak spot.
