Zero Insertion Force Sockets are one of the safest ways to mount IC chips into a circuit. They allow you to drop the chip into the socket, and then secure the legs into place, avoiding damage to the chip.
This is a high-quality, easy to use 28 pin ZIF socket that is 0.3" wide. Makes for easy connecting or programming to DIP ICs. Uses high conductivity terminals create solid connections. Can also be used for smaller pin packages.
