Sterling door closers and floor springs are made at our works in Vasai (East), Maharashtra. Door closer housings are extruded aluminium alloy, precision machined, and painted or powder coated in-house. Each closer uses a rack and pinion mechanism with two-speed control, and the surface-mounted models use universal mounting for left and right hand doors.

Production is managed in an ERP and the products reach the market through a dealer network across India. For projects we size and quote from a door schedule rather than from a price list.

and 2016.

  1. Door closer manufacturing begins

    The business starts making door closers in India, the same operation that MM Efficient Gadget LLP runs today.

  2. MM Efficient Gadget LLP acquires the business

    The LLP takes over the door hardware business earlier known as Sterling Inflowtech Private Limited and Efficient Gadget Limited, and continues it under the Sterling brand.

Made in India,
finished in-house.

  • Extruded aluminium housings, precision machined

    Door closer bodies are extruded aluminium alloy, machined and finished in-house. The FS 3000 floor spring uses an aluminium pressure die-cast housing and the FS 1000 a cast iron body.

  • In-house R&D and test lab

    Design, prototyping and testing happen inside the plant, in the company's own R&D and test lab.

  • Painting and powder coating in-house

    PU painting and powder coating run under the same roof as machining, which keeps finish quality and colour matching under our own control.

  • ERP-managed production

    Production is planned and recorded in an ERP, so project quantities are scheduled rather than improvised.
