Top Plate Stiffener
For plumbing or vacuum system ducting through top plates.
MiTek Top Plate Stiffener
Barwon Timber’s Hardware store stocks the MiTek Top Plate Stiffener. It is suitable for use in conjunction with AS1684 Residential Timber Construction to reinforce a single loadbearing top plate where a hole for a service duct penetration is required, by restoring the top plate to its original design strength.
The Top Plate Stiffener has been designed and manufactured in accordance with ISO 9001 and meets all the requirements of the National Construction Code Series and Australian Standards.
Uses:
- The top plate shall be a single 90 x 35 or 90 x 45 member, and shall be of either MGP10 or MGP12 grade.
- The maximum size of the service duct hole through the top plate shall not be more than 60mm in diameter, and shall be situated between 100mm and 102mm from the face of a stud.
- The TPSA shall be positioned against a stud underneath the top plate when the studs are spaced between 400mm and 600mm apart.
- If the TPSA is too long to fit in between studs (i.e. when they are less than 400mm apart), and if the top plate does not support a truss from above, the TPSA may be fixed on top of the top plate.
Advantages:
- PlateTies can also be used to secure studs in braced panels to comply with Type B bracing specifications.
- As PlateTies have integral teeth, they are very quick to apply and have consistent performance, as nails cannot be inadvertently left out.
- Pre-formed ties ensure tight fit and tight bends, making it easier to fit internal linings.
