The 3000 Series concealed closers offer all the adjustability and control of an overhead closer, with the aesthetic appeal of a concealed device. They are often specified when clean, minimal design is required without compromising on performance - even on ½ hour and 1 hour fire doors.
The closers’ face plate has now been reduced in width to just 32mm. Not only does that mean it looks more unobtrusive than ever, it is also easier to fit as less timber needs to be removed to fit the closer into the door edge. Specifiers appreciate the Astra closers’ understated appearance so it is regularly selected for the most prestigious projects – in fact any scheme where the clunky institutional feel of an overhead closer is inappropriate.
The 3000 series of concealed door closers from Astra is manufactured in the UK, in four different power sizes with adjustable closing speed and latching action for different size and weights of doors. A unique hydraulic piston assembly, designed by Astra, offers an adjustable, controlled rate of door closure together with an adjustable ‘snap action’ for overcoming the latch.
The closers’ quality design and build makes it perfect for high traffic applications, both commercial and residential. Unlike other concealed closers on the market, the Astra 3000 series is fully controlled and adjustable, making it a really viable alternative to overhead products at a sensible price. This adjustability helps specifiers to achieve doors which comply with the Equality Act 2010, Building Regs and PAS 24 for entrance doors and the RRO for fire doors.
The Series 3000 range of closers was developed in-house by Astra. The Size 3 version (3003) is approved to EN1154 (when the power latching action is set to maximum) and CE marked. Fire tests in accordance with BSEN 1634-1:2000 and BSEN 1634-1:1999 have also been carried out making the closers suitable for fire doors. Astra also carries out continuous in-house testing up to half a million cycles.
Astra is well known for its door closer range including the popular Gibraltar range. The Lancashire-based company can demonstrate many years experience in the sector and carries out all of its own R&D in-house. It exports its British door closers all across the globe via a network of distributors and partner companies.
