The new multiple latch “Robusto” makes an innovative contribution to environmental testing chambers. Made of stainless steel, is ideal  for temperature variations from minus 80 to plus 180 degrees Celsius. And so, 7505 scores as an ideal system for extreme temperatures as in environmental simulations or flash freezing. Thanks to its modular design, many latching variations and customised options are available. Robusto can be used as a single or multiple point locking system.

new

In addition to the range of clever options, new items for extreme temperature areas have broaden the product offer, specifically for large doors and high closing forces. To improve the ease of use were not only inserted brass roles into the stainless steel levers, but there are now selective frame parts available in brass too, to allow for higher closing forces. All together an important set of options ideally for climate chambers  and walk-ins with temperatures up to –80 °C / –112 °F.
