How to Install:

Q: How is the RP4B fixed to a hardwood threshold?
A: After cutting the RP4B to length, use a pencil to mark the screw points on the threshold. Ensure you pilot drill the threshold with a 3.5mm drill bit so that the screws are more easily fitted.
Q: How can the RP4B be fixed onto a stone threshold?
A: Once the RP4B is cut to length, place it on the threshold and mark the screw points with a nail and hammer through the fixing points. Remove the RP4B from the threshold. Using a 6mm masonry drill bit, drill each fixing point for sufficient depth to take the fixing screw. Fill each hole with red spaghetti or similar, put the RP4B in place and fit the fixing screws into the red spaghetti. If the stone threshold is not flat, be sure to fix carpenter's packers under the RP4B such that as the screws are tightened, the treadplate remains flat.
Pro Tips:
- Surfaces must be clean and smooth to ensure good adhesion.

FAQ
Frequenty asked questions
Q: What is the Raven RP4B threshold plate made of?
A: The Raven RP4B threshold plate is made of high-quality anodised aluminium which ensures its durability and resistance to wear and tear over time. That is critically important for a treadplate.
Q: How does the Raven RP4B threshold plate help prevent air and water leakages?
A: By creating a flat surface at the door step for a draught excluder to fit snugly to. The RP4B is not preventing air and water, but is facilitating the draught excluder to effectively do its job.

What is a draught excluder?
A draught excluder is a device that seals the gap at the bottom of your door to stop unwanted air, dust, noise, and even pests from sneaking in or out. It’s one of the simplest and most effective ways to improve your home’s comfort and energy efficiency—especially in older homes with gaps you can feel (or even see!).
Why do you recommend Raven draught excluders over other brands?
We’ve tested them all—and Raven comes out on top for performance, durability, and long-term reliability. While they might cost a little more upfront, Raven products last for years, not months. That means less replacing, less frustration, and more value over time. Raven is the draught excluder we installed on our own home, 20+ years ago. Its still there - working - effectively.
Why is Raven more expensive than what I can buy at a hardware store?
Because it’s built to last. Raven products are made with superior materials and are engineered to perform in real Aussie conditions—heat, cold, wind, and rain. Some carry a BAL (bushfire) rating and some carry acoustic ratings, so you’re not just buying a seal—you’re investing in comfort, safety, and peace of mind.
Are cheaper draught stoppers just as good?
Not really. Cheaper options might seem like a bargain, but they often fall off, lose shape, or stop sealing within months, or never work at all. You end up replacing them again and again. With Raven, you buy it once—and it just works, year after year.
Which Raven product is right for my door?
That depends on the size of the gap and the type of door. We’ve done the hard work for you with clear guides and curated product options. Or try Find and Fix My Draughts—it’s our easy tool to help you choose the perfect product for your home.
Can I install Raven products myself?
Yes! Most are DIY-friendly, and we provide installation tips and videos to walk you through it. If you’re comfortable using a drill or screwdriver, you’ll get a clean, professional result—and a draught-free door in no time. If you are not comfortable with DIY, contact us for a referral to a trusted draught proofing technician in your area.
