Serious Steel
Serious Steel Fitness sold a fixed-resistance torsion-spring gripper line under the Steel Grip name. The company is better known for resistance bands and lifting accessories, but retailer and archived product records preserve the gripper line.[1][2]
Steel Grip line
The Steel Grip was offered in six advertised resistance levels:
| Model marking |
|---|
| 100 lb |
| 150 lb |
| 200 lb |
| 250 lb |
| 300 lb |
| 350 lb |
A Serious Steel retailer lists those six strength options together, while surviving product pages describe knurled aluminum handles and six resistance levels.[1][2] The pound values are product labels, not standardized RGC ratings. Owner reviews preserved with older listings also report noticeable variation between examples, reinforcing the need to distinguish an advertised model from a measured specimen.[2]
Serious Steel's instructions recommended avoiding excessive repetitions, moving to the next level after more than 20 complete repetitions, and treating a repetition as complete when the handle bottoms touch.[2] Those are the seller's historical training directions, not a universal gripper-training standard.
Vise adjustable gripper
The brand also sold a Vise Gripper, an adjustable design supplied with two springs and advertised with resistance up to 350 lb.[3] Its design should not be confused with the fixed-resistance Steel Grip line.
Identification and preservation
Known Steel Grip examples use metal knurled handles with the resistance printed on the handle. The grippers have disappeared from much of Serious Steel's current catalog, so retailer pages, product identifiers, collection records, and archived listings are important evidence.
Surviving listings should be read as historical sales material. They establish model names, offered levels, and seller instructions, but do not prove the closing force of an individual gripper.
