VIROTEC®-VSR the ideal storage system
VIROTEC® VSR 24 sprinkler reserve boxes are an ideal storage system for sprinklers, sprinkler spanners and the operating and maintenance manual. The sprinkler reserve box provides space for 24 sprinklers. It has a storage compartment in the side for sprinkler spanners, tools, etc. and a holder in the cover for the operating and maintenance manual. The integrated writing desk rounds off the storage system. VIROTEC® VSR 24 sprinkler reserve boxes are the ideal storage system in the sprinkler control centre.
Due to the writing desk function, VIROTEC® VSR 24 sprinkler reserve boxes should be fitted at a comfortable writing height!
VIROTEC® sprinkler reserve box VSR-24 combine three functions in one. Protects against dust and external influences; the sprinkler compartment (item 1) securely stores up to 24 sprinkler heads in sizes 3/8”, 1/2” and 3/4”. In addition, a side tool compartment (Item 2) of the VIROTEC® sprinkler reserve box VSR-24 provides adequate space for tools and sealing materials such as sprinkler spanners, Teflon tape, small materials, etc. The operating and maintenance manual is securely stored in the loops under the front cover. The front cover can be completely hinged upward and therefore ensures free access to all the storage compartments and the operating and maintenance manual. The practical desk function of the front cover (Item 3) is achieved by locking the hinged clamp (Item 4) in the front cover. The desk edge (Item 5) prevents the documents from slipping off. To close the box, push the hinged clamp (Item 6) upwards and then close the front cover.
