Weightlifter's Warehouse later stated that it had been selling Warren Tetting's grippers since 1992, but an earlier catalog or advertisement has not yet been located to independently document the original 1992 lineup.[^2] 19This capture establishes that the Beef Builder name and a graduated model system were in commercial use by 1999.

40The archived catalogs assigned each model an approximate "pounds pressure to close" figure and a spring-wire diameter. These pressure claims were sales descriptions, not RGC ratings, and should not be converted directly into modern rating values. The catalog itself described the strengths as approximate.[^2][^3] 40The archived catalogs assigned each model an approximate "pounds pressure to close" figure and a spring-wire diameter.

57The 2017 page listed the Super Master at .273 inch, Thor at .406 inch, and Hercules at .5265 inch. Surviving examples and other published lists sometimes differ slightly, so catalog specifications should be identified by date rather than treated as universal measurements for every example.[^3][^5] 57The 2017 page listed the Super Master at .273 inch, Thor at .406 inch, and Hercules at .5265 inch.

61Later Weightlifter's Warehouse catalogs described Beef Builders as using machined steel springs and knurled aluminum handles.[^2][^3] The 1999 capture instead specified steel handles, documenting at least one material change during the life of the line.[^1] 61Later Weightlifter's Warehouse catalogs described Beef Builders as using machined steel springs and knurled aluminum handles.[^2][^3] The 1999 capture instead specified steel handles, documenting at least one material change during the life of the line.[^1]

63A secondary product guide reproducing Weightlifter's Warehouse information described both 3/4-inch and 5/8-inch handle options. It also listed optional spring-to-handle gaps of 1/16, 1/8, 3/16, and 1/4 inch, along with standard and reduced handle spreads.[^4] Collector records additionally document narrow-spread, extended-handle, smooth-handle, and other custom examples. 63A secondary product guide reproducing Weightlifter's Warehouse information described both 3/4-inch and 5/8-inch handle options.

75### Revolving-handle customs

77Collector Joe Musselwhite reported owning a Tetting revolving-handle prototype dating to late 2008 and commissioning a single-revolving-handle version in 2009. His January 2013 account describes comparing the two configurations with other grip athletes. These were custom experimental grippers, not a documented numbered retail edition.[^9]

77Surviving Tetting grippers show several marking and construction styles. A community research timeline maintained by Matt Cannon distinguishes early letter-stamped grippers, named models with fine knurling and larger bottom bevels, Thor-stamped examples, later blank-handle examples, and a short straight-line Thor-stamp period.[^5] 81Surviving Tetting grippers show several marking and construction styles.

79Many dates in this chronology remain provisional. The timeline's author explicitly describes it as an evolving record and identifies where more receipts, correspondence, archived pages, and dated photographs are needed. Gripperpedia therefore does not assign an exact year from appearance alone. 83Many dates in this chronology remain provisional.

81The model initials often corresponded to the name, such as **SM** for Super Master, **GM** for Grand Master, and **E** for Elite. Stamp placement and style changed, and blank or unusually stamped handles are not automatically evidence that a gripper is counterfeit or misidentified.[^5] 85The model initials often corresponded to the name, such as **SM** for Super Master, **GM** for Grand Master, and **E** for Elite.
