Lock-It Servo Cables feature our unique "hook" molded into the male connector that locks the cables together for a solid and secure connection that won't vibrate loose in flight.  They eliminate the need for a separate servo lead lock or clip, and are easy to release when you need to.  In addition to the locking hook, the male connector is made to accept both the universal "beveled" style female connector found on JR, Spectrum, and Hitec servos, as well as the "tabbed" style female connector used by Futaba servos.  And the female connector is the universal "beveled" style, making our Lock-It Servo Cables the ONLY truly universal servo cables on the market.  Available in servo extensions and servo Y cables, and in most popular lengths.
