Pet products

Dog leash and harness hardware

Snap hooks, D-rings, buckles and adjusters for collars, leashes and harnesses, in zinc and iron. Lightweight aluminum hardware is also available as an import.

Double-locking snap hookA utility-model registered design in Korea. The gate opens only after the locking cap is slid down, so it does not open easily when it catches or gets pressed on a walk.

Welded iron ringsOur D-rings and O-rings are welded closed, so they hold up when a dog pulls hard. Sizes for large dogs are available.

Korean plating

Made where it costs less, finished in Korea

Parts can be cast in Korea or overseas. Plating, which decides the final color and finish, is done in Korea. Many brands choose this to keep costs down while getting Korean plating quality.

High-grade plated parts are 100% inspected before shipping. Standard-grade parts are sample-inspected.
