Sintex top-hinged SMC junction boxes have the door fixed to the base with hinges on top. When opened, the door lifts up and stays clear of the work area. Sintex describes its SMC boxes as shockproof, rustproof, weatherproof, fire retardant and tamper-proof, with cable entry from the bottom and sides. The Sintex brochure lists two top-hinged sizes. GSJB-1616-T (155 x 155 x 100 mm) is for single-phase, two-core, low-wattage pathway lighting. GSJB-3016-T (275 x 135 x 110 mm) is a pole-mounted box for three-phase, four-core, high-wattage road and street lighting, for industrial and commercial use as well as flood lighting. Contractors fit these boxes at light poles and outdoor feeder points. Buy from Monika Electro Tech (a Monika group firm), an Authorised Stockist of Sintex in Ahmedabad.
