• Quick installation (45 sec. per penetration) from
above requiring only a cordless drill driver
•
No welding certificate or hot-work precautions
required
•
Can be installed by one man alone

NO MORE WELDING!
BLÜCHER has developed an entirely new solution for installing flanged drains
and penetrations in steel structures by means of a patent-applied screw-lock
system.
Installation of a penetration in just 45 seconds!
How it works
Drains and penetrations come with a special screw-lock system with sealing
ring for each fixing point and a sealing ring for the entire drain/penetration.
Installation can be carried out from above using an electric drill/screwdriver
and/or a torque wrench, tightening all fixings to 35 Nm.
Range
Flanged lower parts types 470 and 475
Flanged single-pipe penetration type 868, sizes 50, 75 and 110 mm
Flanged jointing unit with group penetration type 490.
Material
Stainless steel - AISI 316L
