On offer is this twin socket telephone extension reel which has 15 metres of cable & also a loose extension cable that is 10 meters long. Also included are 2 duel doublers. The loose cable has a small, app 12mm section of insulation, not the wiring, that I’ve had to bind with insulation tape as it got trapped in a door jamb & it was only when we changed the ‘phone system, that I realised it, but it certainly doesn’t detract from its use.
