What is a PCB Card Guide?
Printed circuit board (PCB) card guides, also called PCB retainers, are short narrow strips of material formed into shallow tapered troughs. PC boards are inserted into the top of the trough while the bottom is secured to an enclosure wall. Most card guides secure the PCB in place through the use of pressure but some card guides utilize levers or screws to lock the PCB in place. Card guides are fabricated from a variety of materials including nylon, aluminum, beryllium copper, and stainless steel. By securing circuit boards in place, card guides prevent damage to PCBs caused by vibration and movement.
The Top Names in Card Guides
For many years Pentair, under their Schroff, Birtcher, and Calmark brands, has been the leading manufacturer of PCB card guides. In fact, many of their branded products such as Wedge Tainers, Lok Tainers, PCB Tainers, and Card Loks have become synonymous with PCB card guides. Other top card guide manufacturers include Bivar, Essentra (formerly Richco), and Keystone Electronics.

Essential Hardware: PCB Card Guides
Card guides are key to the performance and reliability of most electronic devices. Card guides attach to the edges of printed circuit boards (PCBs) securely holding them in place. Since card guides are used in nearly all electronic applications they must meet the demands of many different environments. Card guides can be found in applications ranging from military communication equipment to network servers.
PCB card guides typically come in two primary mounting configurations: vertical and horizontal. Card guides are also available in many different materials, sizes and locking configurations. Other variations include card guides specifically designed for high vibration or static sensitive conditions.

Protecting & Organizing Wire Using Cable Clamps
What is a Cable Clamp?
Cable clamps play an important role in guiding, organizing, and protecting wire and cable. As the name indicates, cable clamps utilize pressure to bundle and secure cables and wires in place. Cable clamps are first fastened to a panel, often using a snap-in fastener, screw, or adhesive. Once the clamp is secure the cable is pressed into place. Depending on the clamp configuration the cable can be inserted from the top, side, or bottom of the clamp.

Reducing System Wear Using Anti-Vibration Mounts
If you’ve ever driven in an old truck you probably remember feeling like you hit every bump and divot in the road. That’s likely because the technology used to reduce motion and vibration in the truck was outdated. Vehicles today are equipped with advanced shocks and vibration mounts to reduce the amount of motion felt by drivers and passengers. These advancements in motion control aren’t just limited to commercial automobiles. In fact, motion control technology is utilized in all kinds of applications from industrial machinery to medical devices. Some of the simplest and most widely used motion control solutions are bumper feet and vibration mounts. These devices dampen vibration using springs and dense materials like rubber.
Why Use Vibration Mounts & Bumper Feet
- Increased system longevity by reducing stress on components
- Improved usability and increased precision
- Cost savings over the life of the application
bisco + Essentra = Your Source for Motion Control Solutions
