Set of E27 lamp holders for flat incandescent lamp cable, for making string lights. Installing the lamp holders on the cable is simple; thanks to the push-in contacts, there is no need to strip the wire. The procedure is as follows: Place the socket on a stable surface and push the cable into the designated area onto the push-on pin contacts. Once the cable is connected to the contacts, secure the cable cover with two screws. The sockets meet the IP44 protection rating thanks to the silicone gasket.
