Card-Lok/Wedge-Lok Retainers


Schroff offers a wide variety of retainer products from economical nylon card guides to high-performance Card- and Wedge-Loks

Schroff CALMARK and BIRTCHER Card- and Wedge-Lok retainers are designed to retain printed circuit boards. Schroff offers a wide variety of retainer products, from economical nylon card guides to high-performance Card- and Wedge-Loks, to meet the needs of different applications; whereas nylon card guides and PCB tainers are typically used in lower shock and vibration environments, Card- and Wedge-Loks are designed for rugged applications. Offering a wide range of retainers, Schroff can provide a reliable protection solution for diverse applications, including cold wall, sheet metal, or non-machined cold wall designs.

Features and Benefits
  • Over 50 years of experience with the largest library of retainer products
  • Wide variety of products to meet the needs of most any PCB retention requirement
    • Nylon card guides are ideal for static electronics, and provide a simple and economical way to secure boards
    • PCB Tainers are ideal for lower shock and vibration environments with sheet metal applications, and offer spring action card retention
    • Lok Tainers can be used in moderate shock and vibration environments, in either sheet metal or cold wall applications, and utilize a cam and lobe design for board retention
    • High-performance Card- or Wedge-Loks provide the highest level of board retention and conduction-cooling thermal performance for rugged, high shock and high vibration environments. Card- and Wedge-Loks are used in cold wall applications, and can be either screw or lever actuated.
  • Many options to configure standard products; most products have options for length, board thickness, finish, and mounting options
