The weights are calculated for round steel brackets without nuts and washers.

1) Approximately corresponds to the outside diameter of the associated pipe plus the permissible dimensional deviations.

2) collar, are minimum dimensions and apply to a panel thickness of 10 mm. Dimensions that deviate from those in the table must be specified when ordering; The designation is then for a round steel bracket shape 130 mm and a clear diameter of 82 mm and z. B. h b- 55 mm:

Round steel bracket A 82 x 130 x 55 DIN 3570

Avoid sizes in brackets if possible.

Material:

1. for round brackets:   USt 37-1 according to DIN 17 100 semi-finished product to be used round steel according to DIN 1013

2. for nuts:  strength class 8 according to DIN 267 sheet 4
