Sterling door closers.
Two speeds, one arc.

Rack and pinion door closers, and floor springs, all with two-speed control: the closing speed governs the swing, the latching speed the last part of travel. Manufacturing door closers in India since 1989.

Product families

Made in our own
plant in Vasai.

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.

  • 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.

  • ISO 9001:2015 quality system

    Manufacturing runs under a certified ISO 9001:2015 quality management system.

  • UL-audited facility

    The manufacturing facility has been audited by UL.

  • ERP-managed production

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

Mounting

For a door of 75 kg and 1050 mm

EN 4

  1. 75 kg is over 60 and up to 80 kg: EN 4 by weight.
  2. 1050 mm is over 950 and up to 1100 mm: EN 4 by width.
  3. Both give EN 4, so EN 4 governs. Where they differ, the larger size governs.

Where are Sterling door closers and floor springs made?

At MM Efficient Gadget LLP's own ISO 9001:2015 certified, UL-audited facility in Vasai-Virar, Maharashtra. The business has made door control hardware since 1989.

Are Sterling door closers ISI marked?

Yes, all eight. The DC 1500, DC 1800 LA, DC 1820, DC 2000, DC 2600, DC 2700, DC 2800 and DC 2900 door closers are ISI marked to IS 3564:1995 under BIS licence CM/L No. 7700126309. Floor springs are certified separately: the FS 1000 and FS 3000 are BIS certified under licence CM/L No. 7700249814. Each product page states the marking and the cycle test figure that apply to that model.

Which Sterling model do I need for my door?

Size by door weight and leaf width. Up to 45 kg: DC 1500 (EN 1-2). Up to 60 kg: DC 1800 LA or DC 1820, or the concealed DC 2700 (EN 2-3). Up to 80 kg: DC 2000 or DC 2600 (EN 3-4), or the concealed DC 2800 (EN 2-4). Up to 100 kg: DC 2900 (EN 4-5). For glass or heavy doors, the FS 1000 floor spring covers 60 to 80 kg and the FS 3000 covers 90 to 120 kg.

Do you quote for projects and bulk orders?

Yes. Sterling does not publish list prices, because the price depends on the model, finish and quantity. Send a door schedule with leaf widths, door weights, mounting type and quantities, and we will size and quote every door against it.

How do I become a Sterling dealer?

Apply on the dealers page with your firm name, city and contact details, or call or WhatsApp +91 83693 92225. Our team will get back to you to discuss the range and supply.

How do I adjust a door closer's closing speed?

Door closers have two small adjustment valves, usually marked "Close" and "Latch". Turn them slightly, about 1/8 turn at a time, with a screwdriver: clockwise to slow the door down, anticlockwise to speed it up. Closing speed controls the swing from open to about 10 to 15 cm before the frame; latching speed controls the final click as it shuts.
