Softalk 21000 Phone Cord Detangler White Landline Telephone Accessory Fits standard handsets and handsets with recessed jacks up to 5/8" deep that standard size detanglers may not reach. Prevent the frustration of twisted, knotted and tangled coil phone cords. The no-tools-required Cord Detangler rotates 360 degrees to prevent your coil phone cord from tangling. Gold-plated metal contacts prevent loss of sound quality. Make sure to click the device all the way in and it isn't too short for the handset (refer to alternate image). For phone handsets with jacks deeper than 5/8",please try item B01D75JD20 which fits jack up to 3/4" deep
