Pentair Introduces New High Thermal Performance Retainer Series and Newly Expanded High Clamp Force Family of Card Loks
High Clamp “HC” Card Lok
High Thermal “HT” Card Lok
Pentair has released a new Schroff retainer design-the Calmark High Thermal “HT” Card Lok and the newly expanded family of Calmark Series 263HC, 265HC, and 276HC High Clamp Force Card Lok Retainers.
The 280HT Card Lok provides best-in-class thermal performance by up to 15 percent over similarly sized Card Loks. The 280HT can do this by shortening the thermal path distance from the PCB to the cold wall through a unique design.
Unlike the traditional Card Lok, the 280HT Card Lok features solid brackets along the length of the Card Lok that provide a continuous and uniform surface along the printed circuit board, or heat frame, and the cold wall. The internal geometry maximizes surface contact area while minimizing heat path distance from the board to the cold wall. You can view data sheet, performance data, and CAD files here.
The newly designed 263HC, 265HC, and 276HC High Clamp Force Card Lok Retainers provide an average of three times the clamping force of similarly sized Card Loks, meeting the growing demands of shock and vibration environments. Its small and lightweight design provides industry-leading board retention that is ideal for defense, space and aerospace applications.

Product Spotlight: Schroff 42 Series Wedge Loks
Introducing Heavy Duty PCB Retainers
Schroff (formerly Birtcher) is the global leader in the design and manufacturing of heavy duty PCB retainers and card guides. One of Schroff / Birtcher’s most popular PCB retainers is the 42 Series Wedge Lok. The 42 Series Wedge Lok is designed to secure PBCs in rugged and high vibration environments. 42 Series PCB retainers also offer a lightweight design making them ideal for military, defense, and aerospace applications.
42 Series Wedge Lok Key Features
- Designed for cold wall applications
- Aids thermal transfer from the PCB to the cold wall
- Screw actuated
- 3 segment, non-shafted design
- Average clamp force (5″, black anodized) = 269 lbs
- Max expansion 6.98 mm (.275 in)
- Flexible mounting options
- Available with gold chem film, clear chem film, black anodized, hard black anodized, or electroless nickel plating

Installing 42 Series Wedge Loks
42 Series Wedge Loks are designed for installation in cold wall applications. During installation Wedge Loks are first attached to the top and bottom of the PCB. Once the PCB is secured between the Wedge Loks it is inserted into cold wall channels in the card cage. Finally the Wedge Lok is actuated clamping the PCB to the cold wall.
Configuring 42 Series Wedge Loks
Schroff / Birtcher 42 Series Wedge Loks are highly customizable helping them meet diverse and challenging application requirements. To configure a 42 Series PCB retainer for your application view the 42 Series spec sheet.
