Made from UV-stabilised grey ABS, it's built to withstand years of outdoor exposure — sun, rain, and frost — without cracking or fading, keeping the copper connections inside safe from moisture and corrosion that would otherwise lead to crackly lines or dropped broadband.\nAt roughly 125 x 90 x 42mm, it's compact enough to mount discreetly on an exterior wall, fascia, or pole, yet roomy enough to house multiple gel-filled crimps or block terminals. Three cable entry points accommodate leads up to 12mm in diameter, giving plenty of flexibility for routing an incoming supply alongside extensions or repaired sections. The slide-on lid locks down with a single centre screw, sealing out the elements while remaining easy to access for future maintenance.\n\nBecause it matches the official BT\/Openreach design, it's the right choice for anyone maintaining or extending a BT, Sky, or Virgin Media phone line — using a genuine-spec enclosure helps keep the installation consistent with engineer standards, reducing the risk of faults and the need for costly call-outs. It's equally useful for splicing a damaged or severed external cable run, making it a practical repair kit as well as a termination point.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eEAN:\u003c\/b\u003e 5060583537787\u003c\/p\u003e\u003cp\u003e\u003cb\u003eModel:\u003c\/b\u003e 66BJB\u003c\/p\u003e\u003cp\u003e\u003cb\u003eItem Condition:\u003c\/b\u003e New\u003c\/p\u003e","brand":"1STec","offers":[{"title":"Default Title","offer_id":60019340444032,"sku":"9J-9TVC-9PA9","price":9.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0576\/3688\/0555\/files\/613xZzJeM-L.jpg?v=1790856963","url":"https:\/\/1stec.co.uk\/products\/grey-bt66b-external-use-junction-box-electrical-enclosure-to-fit-on-wall-eaves-for-outdoor-telephone-wiring-overhead-drop-wire-jellys-gel-crimp-housing-openreach-broadband-main-dropwire-supply-lead","provider":"1STec","version":"1.0","type":"link"}
