I acquired my Krok Cable Lock from Gear4Rocks in 2012. Gear4Rocks is the same company as Krok, the only difference is that the Krok trademark sells gear only inside the Ukraine, and the Gear4Rocks trademark was created to spread Ukrainian gear around the world.
The Krok Cable Lock is 130 mm. tall, 78 mm. wide, 19 mm. thick, and weighs 487 g.
The Cable Lock consists of two connected cams mounted in a steel shell. The unique shell grooves allow the unit to be attached to a cable without opening or disassembling the unit.
There are no markings on this device.
The Cable Lock is designed to be used on 8 mm. wire cable. It appears to be a copy of the Protecta International AC350 Cabloc.

I acquired my Krok Rope Lock Lite from Gear4Rocks in 2013.
My Krok Rope Lock Lite is 85 mm. long, 108 mm. wide, 23 mm. high, and weighs 307 g. It is similar to the Cable Lock, but smaller, and has a painted finish.
The front connecting arm is stamped with the Krok logo and a book-with-an-"i" icon.
I don't like painted devices because paint tends to wear off, leaving a mess on my ropes.

Technical DetailsI acquired my Bark-A from Krok in 2021.
My Bark-A is 68 mm. long, 75 mm. wide, 33 mm. high, and weighs 133 g.
The front is printed with the Krok logo, a hollow up-pointing arrow with "WLL 12 kN" inside, ’"Барк-А",’ "8<Ø<13," a book-with-an-"i" icon, and "1803.1605."
The Bark-A is a manual positioning device that falls under EN 12841 Type B. EN 12841 techniques are not normally used by cavers, who long ago tried and abandoned those ideas as impractical and creating greater hazards than they address. The differences between Type A (safety line adjustment), Type B (working line ascender) and Type C (working line descender) rope adjustment device terminologies in EN 12841 do not translate well into my caver/climber-oriented classification, so I'm just calling this a rope grab.
Using a bolt as the cam axle greatly reduces the likelihood of the device inadvertently coming off rope. The shield around the nut interferes with using a normal wrench (one needs a socket), which helps keep the user from putting the device on rope or taking it off. This makes the Bark-A impractical as a sporting ascender, but that is not its intended use.
The "-A in "Барк-А" refers to the aluminum shell version. There is also a steel-shell Барк-Ст.

Technical DetailsI acquired my Brig-A from Krok in 2021.
My Krok Brig-A 3606_2772.59 (Бриг) is 81 mm. long, 73 mm. wide, 37 mm. high, and weighs 168 g.
The front is printed with the Krok logo, a hollow up-pointing arrow with "WLL 12 kN" inside, ’"Барк-А",’ "10<Ø<18," and "1803.1605." The rear is printed with "TP TC 019/2011," "EAC," a book-with-an-"i" icon, and "ГОСТ EN 12841-2014."
I'm calling the Brig-A a rope grab for the same reason I gave for the Bark-A.
The Brig-A is a larger version of the Bark-A, suitable for the "bigger-is-better" crowd. Like the Bark-A, the Brig-A is impractical as a sporting ascender, but that is not its intended use.
The "-A in "Бриг-А" refers to the aluminum shell version. There is also a steel-shell "Бриг-Ст"

Technical DetailsI acquired my GAL-15 from Krok in 2021.
My GAL-15 is 90 mm. long, 110 mm. wide, 36 mm. high, and weighs 392 g.
In addition to the axle bolt, the GAL-15 has two 5 mm. shoulder bolts through the shell from rear to front, where they are secured by 5 mm. nylon lock nuts. The top bolt passes through a 17.8 mm. o. d. roller. The lower bolt limits how far the cam can open.
The rear is printed with the Krok logo, a hollow up-pointing arrow with "MBS 15 kN" inside, ’СУ "ГАЛ-15",’ "EN 12841/B," "Мах 600 кг", 12<Ø<16," "TP TC 019/2011," "EAC," a book-with-an-"i" icon, the Ukrainian Conformity Mark, and "20.10.09.01."
"ГАЛ" stands for "гибкая анкерная линия" (flexible anchor line), which is unfortunate since it overlooks the nautical theme that a Barque-Brig-Galley naming sequence would provide. "СУ" stands for "Спусковое Устройство" meaning "descender device," which is rather odd for a "working line ascender" as defined by EN 12841/B. I'm calling this a rope grab like the other non-nautical devices.
The roller is opposite the spine of the shell, and so its only apparent function is to help guide the GAL-15 on the rope. It does not reduce friction under load; for that it would have to be placed on the shell side of the rope (e.g., see the Gibbs roller cam modifications).
The cam limiter is also unnecessary, since anything tied or clipped to the cam will limit the cam motion equally well.
The GAL-15 is impractical as a sporting ascender, but that is not its intended use.
