10Micron GM4000 BHP Steel Levelling Flange

This Baader BHP levelling flange is the 100 mm-high version for GM4000 / PlaneWave L-350. Its exact manufacturer part number is 2451185; the published net weight is 28 kg.

Levelling close to the mount

The flange compensates unevenness in the foundation or pier and deviations from the required north-south orientation. Adjustment is made near the mount so the supporting pillar can remain rigid.

Steel construction

Two solid steel plates are separated by six steel bars. The top plate is precision-milled and threaded for the specified mounting interface, providing a defined support surface for the mount assembly.

Required interfaces

The listed mount interface is GM4000 pier flange 1454090 / 10M4090. Use it with the compatible Baader BHP pillar or another properly prepared support.
