Adjustable Handles

User-friendly and ergonomically shaped, adjustable handles are the ideal solution to situations that demand more torque than standard knobs. Easily customizable, this hardware can be adjusted to a wide variety of applications, including heavy duty projects and situations with tight spaces.


Ball, star, quick fastening, and knurled knobs are just the beginning of AFI’s selection of grip solutions. We stock custom knobs in a full range of shapes, sizes, and materials to operate latching, locking, and grip mechanisms, each of which enhances precise operation.


When mechanical parts need to be held, latched, or aligned, plunger components provide the solution. By utilizing spring pressure, plungers remain nested between components to hold a desired relative position. AFI’s selection features components with specialty performance benefits such as cam action, lockouts, and more.


These mechanical fasteners join surfaces together with a two-part hardware design, with a keeper or strike component mounted on one work surface and the latch on another. Some offer locking or recessed design features, with designs in both specialty plastics and metals.
