A portable closer for prepared round seams
Start with the joint and access
The H-E reference describes round ducts and compatible fittings. Confirm the prepared longitudinal profile and the tool access along the entire joint.
Do not assume rectangular Pittsburgh suitability from the electrical drive or the sheet-thickness entries.
Portability and workpiece geometry are different checks
6.9 kg reference
Review the handling position and support needed for the actual duct or fitting.
6–10 m/min reference
This is the listed working-speed range. Loading, seam preparation and inspection affect finished output.
Prepared seam
Form and assemble compatible edges before the powered closing operation. The closer is not a lock former.
H-E Supplied Reference Entries
| Model | H-E |
|---|---|
| Rated Voltage | 200 V / 50 Hz |
| Load Power | 1800 W |
| Working Speed | 6–10 m/min |
| Weight | 6.9 kg |
| Minimum Internal Radius | ≥150 mm |
| Minimum External Diameter | ≥150 mm |
| Working Thickness | 0.4–1.0 mm / 0.75–1.25 mm |
The source lists both minimum internal radius and minimum external diameter at ≥150 mm, plus two thickness entries. Confirm these geometric definitions and configuration mapping, and the unusual listed 200 V / 50 Hz supply, in writing.
A useful fitting trial
- 01
Prepare joint
Use the actual grade and mating profile.
- 02
Check access
Include the smallest difficult fitting.
- 03
Close seam
Demonstrate supported operation along the full joint.
- 04
Inspect result
Check closure and project-required sealing.
Questions to settle before ordering
Is it for rectangular Pittsburgh seams?
The source describes round ducts and compatible fittings. Other applications require confirmation.
Does it form the original lock?
No. Plan the prepared profile and assembly before closing.
Is ≥150 mm a universal diameter rule?
The source uses both radius and diameter labels. Obtain a drawing and written definitions.
Which thickness entry applies?
Confirm the quoted configuration against the two supplied ranges and your grade.
What electrical standard is listed?
200 V / 50 Hz appears in the reference. Confirm the actual destination supply before ordering.
