Clamp Types
NORMAFIX® HMK
Heavy-Duty design
For HMK heavy-duty clamps the ends of the brackets are folded
back and spot welded onto the clamp band. Thanks to this
design the clamps are suitable for fastening heavy-weight con-
tainers and pipes and they able to withstand high mechanical
loads. The heavy-duty clamps are available in single-part or
two-part design and in 30 mm band width.
All clamps in this range are equipped with a rubber profile.
NORMAFIX® HMK
Standard design
HMK standard clamps with “open” bracket are suitable for use
in applications where relatively light-weight pipes and contai-
ners need to be retained and which involve low mechanical
loads. Standard design retaining clamps with brackets are avai-
lable as single-part or two-part design. The clamp band is either
15, 20 or 25 mm wide. If vibrations need to be absorbed, an
additional rubber profile can be supplied which is also suitable
for use as gasket against creeping water.
NORMAFIX® K
NORMAFIX® K are pre-fabricated steel brackets that are suitable
to convert any NORMACLAMP® standard clamp (A, GBS, HD, SP
or TORRO®) into a retaining clamp with bracket: Just open the
clamp, then push the clamp band through the slot of the bracket
- that’s it.
NORMAFIX® K brackets are made from W1 steel and are also
available in K1 geometry.
