Technical Details

I acquired my Ace Metal Products FP-7202G-3-LG-2-1 from Hardware Sales in 2010.

My FP-7202G-3-LG-2-1 is 68 mm. long, 124 mm. wide, 24 mm. high, and weighs 454 g.

The FP-7202G-3-LG-2-1 is made from a number of plated steel stampings and minor parts. One 2.5 mm. plate forms a 3/4-circle rope channel, and extensions tabs on the sides are bent to support the cam axle pins. The tabs expand outward between the two pins. There are two cams, and two dimples in the shell, one opposite each cam. Each cam is made from two steel stampings riveted together. One 3 mm. stamping is folded to form the two sides of the cam, and a 5.5 mm. stamping forms the center. Each cam has 8 V-shaped notches on the side stamping, forming 9 teeth on each side of each cam. The center cam plate also has 8 V-shaped notches forming 9 teeth, but these are not aligned with those on the side. The cams are connected by a 2.2 mm. stamped channel with a stamped knurl pattern for better grip. The connections and cam axles are all rivets. Springs on the channel pivot pins act to close the cams. A 4.9 mm. stamped eye with a 25.7 mm. hole pivots from the pin connecting the channel and lower cam. This is the tie-in point.

One side of the shell is stamped with 'ROPE:5/8"(16mm)', an up-pointing arrow labeled "UP," "INSPECT BEFORE EACH USE!," "25kN 7103 ANSIZ359.1," and an icon of some sort. The eye piece is stamped "09 8."

Comments

The FP-7202G-3-LG-2-1 closely resembles the Super-Anchor-Safety 4015M. There are differences in detail, such as the flared tabs, the toothed center cam plate, and a different spine knurl pattern, but the pronounced similarities make me suspect a common source.

The dual cam is similar to that on some of the Miller 8174 rope grabs, but like the Mittleman KB2 and unlike the Miller 8174s, this one cannot be opened to allow rigging at the middle of the rope. To rig this one, the user has to thread one end of the rope through the device.

I acquired my Ace Metal Products FP-7103G-S Presto from Hardware Sales in 2010.

My Ace Metal Products FP-7103G-S Presto is 99 mm. long, 130 mm. wide, 65 mm. high, and weighs 584 g.

The Presto is made of stamped steel like the Komet and Miller rope grabs. It operates on the same principle as a Type 1 Lever Cam Ascender. The cam is made of 5 pieces of sheet steel riveted together, providing an unusual tooth pattern (at least for an ascender). The more interesting feature is how the frame opens to accept the rope. The frame is hinged, and a threaded knob that secures the back of the frame when it is closed. A spring-loaded lever engages a groove in the knob's bolt, keeping it from opening. One must depress the lever to open or close thePresto.

The Presto has a hard plastic roller above the cam. This reduces friction in the same way as the rollers on the Komet rope grabs or the Lewis ascender. A gravity lock helps prevent closing the Presto if it is inverted.

The rear plate is stamped with an up-pointing arrow labeled "HAUT," "UP," "OBEN," and "ALTO;" "PRESTO™," 'ROPE:1/2"~5/8" (13mm~16mm),' "INSPECT BEFORE EACH USE!," "25kN PT 7202," "ANSI z359.1," and an unknown icon. The side with the lever is stamped "PRESS TO OPEN/CLOSE." The eye is stamped "07 A2."

Comments

One of the key features of this particular rope grab is the gravity lock. The gravity lock is a lightweight steel piece that slides on the hinge pin. When the device is right-side-up, an ear clears a notch in the rear channel, allowing it to open easily. When the device is inverted, gravity pulls it out of alignment with the notch. Unfortunately, a mild shake is all one needs to realign the pin. Once again, my personal preference is to rely on doing things right rather than on gadgetry for safety. Thanks to Christer Hogne for pointing this out to me.

The Presto is essentially the same as the Climb Tech and closely resembles the Tractel Stopfor S. One key functional difference is that the Presto's closure bolt lacks the tapered end found on the Tractel Stopfor S, so one must depress the lever to close the device.
