The component is bolted to mounting rails with a width of
41 mm to create brackets for wall, floor, and
ceiling mounting or supports for frame structures.
Component fully pre-assembled for single rails.
The diamond-shaped base plate allows for high
bending moments and secure support of
transverse loads.
Load diagrams: see catalog data sheet
Payload for wall mounting:
see catalog data sheet; these apply to walls when
using two screws of the specified
load class.
Payload for ceiling mounting:
Max. permissible Fq = 7.0 kN for ceiling mounting in vertical
direction with at least one bolt-through screw
(8.8)
Tensile payload for ceiling mounting:
41/21-31 to 41/41-45: Fz = 2.0 kN
The prerequisite for the load values is the
proper assembly of all enclosed
individual parts.
For ceiling mounting, we recommend using at least one
bolt-through screw for higher loads (up to 7 kN) (for
examples, see Sikla Mounting Technology, Chapter 2).
Tightening torque M:
41/21-31 to 41/41-45: 40 Nm
Material: Steel, electro-galvanized
Make: WBD 41 - 21-32
