Practical testing to support clearer installation guidance
Correct hanger installation relies on more than choosing the right connector. The fixing method, fastener placement and manufacturer requirements all play an important role in helping the connection perform as intended.
Dindas Australia recently completed internal prototype testing to assess the suitability of using a Paslode Impulse PPN Master positive placement nailer for BIH237x45 I-Beam Hanger installation.
The purpose of the testing was to assess whether this fixing method could provide a suitable alternative to conventional manual nail fixing for the tested BIH hanger configuration.
What was included in the test?
The prototype test assembly included Dindas LVL13.2 members used as joist and bearer components, with Dindas LVL15 used as lateral restraint members.
The tested fixing method included:
- BIH237x45 I-Beam Hangers
- Paslode Impulse PPN Master positive placement nailer
- 3.75 x 40 mm mechanical galvanised hardened R-head positive placement nails
The fasteners used in the prototype testing matched the size specified by the connector manufacturer for the tested hanger.
Why positive placement matters
Positive placement nailers are designed for installing metal connectors and hangers with pre-punched holes.
The positive placement probe helps align the nail with the hanger hole before firing. When the tool is set up and used correctly, this can help support:
- More consistent fastener placement
- Fewer missed holes
- More efficient hanger installation
- Less rework caused by incorrect nail placement
- Better mobility compared with compressor and hose-based setups
As with any fixing method, the final outcome depends on correct tool setup, operator training, tool maintenance and following the relevant connector and fastener requirements.
What the prototype testing showed
The assessment was based on internal prototype testing.
During the testing program, the BIH hanger system was assessed under the required prototype testing process. Based on the completed testing, the BIH hanger system satisfied the acceptance requirements specified in AS 1720.1 for prototype testing.
This supports the suitability of the tested positive placement fixing method for the specific BIH237x45 hanger configuration assessed by Dindas Australia.
Practical considerations for installers
The tool evaluation also highlighted several practical considerations for teams using positive placement nailers.
Before using this type of tool, installers should consider:
- Operator training and familiarity with the tool
- Correct seating of the positive placement probe
- Routine cleaning and maintenance
- Battery and fuel cell management
- Availability of spare consumables
- Appropriate PPE, including eye and hearing protection
- Confirmation that the selected fasteners match the connector manufacturer’s requirements
These points are important because a positive placement system can only support installation quality when it is used correctly and in line with the relevant documentation.
Important scope note
This article refers to a specific internal prototype test completed by Dindas Australia using the BIH237x45 I-Beam Hanger, Paslode Impulse PPN Master positive placement nailer and nominated positive placement nails. It summarises the public-facing outcome only and does not replace the full test report, connector manufacturer documentation, project design information or installation requirements.
The result should not be treated as a general approval for all hangers, fasteners, tools, timber members or site conditions.
For project-specific requirements, always refer to the current connector manufacturer’s installation documentation, relevant design information and project requirements.
