Important Cylinder Information:

⚠️ Critical Installation Requirement: If you're replacing an external pull handle with this blanking plate (removing outside access completely), you must change your existing full euro cylinder to a half cylinder. Here's why: A full euro cylinder extends through the entire door thickness with keyholes on both sides. When you fit a blanking plate with no handle, the full cylinder would be too long as there is no cylinder hole on the blanking plate. A half cylinder only operates from the inside and has a solid, blank face on the outside, sitting well behind the blanking plate. This configuration also improves security by eliminating the external cylinder that could be attacked or manipulated.

Pro Tips:

Pro Tip: Before ordering, carefully measure your existing backplate dimensions and confirm the screw centre spacing is exactly 154mm using a tape measure or ruler. Check the technical diagram in the product gallery to identify the correct measurement points. For the best aesthetic match, choose the same finish as your internal patio door handle—Polished Chrome for a bright, reflective finish, Satin Chrome for a contemporary brushed look, White for uPVC door frames, or Black for modern, bold styling. If you're removing external access completely, remember to order a compatible half cylinder at the same time to avoid delays in completing your installation.

Package Contents:

• 1 × GreenteQ Alpha external blanking plate in your selected finish (154mm screw centre spacing)

Available in: Black, Polished Chrome, Satin Chrome, or White

Installation Guide:

1. Preparation: Remove the existing external handle or backplate by unscrewing all fixing screws. If converting to inside-only access, ensure you have a half cylinder ready to install.
2. Cylinder Replacement (if applicable): If fitting a blanking plate where a pull handle previously existed, remove the existing full euro cylinder and replace it with a half cylinder from the internal side of the door.
3. Position Blanking Plate: Align the blanking plate over the existing screw holes, ensuring the 154mm screw centres match perfectly. The plate is reversible, so orientation doesn't matter.
4. Secure Fixings: Insert screws through the blanking plate into the door frame. Tighten evenly in a cross pattern to ensure even pressure and proper alignment.
5. Final Check: Verify the plate sits flush against the door surface with no gaps. Test the internal handle operation to ensure smooth functionality.

Note: Fixings not included. Reuse your existing screws or purchase appropriate exterior-grade screws separately if needed. Ensure screws are suitable for outdoor use to prevent corrosion.

Frequently Asked Questions:

Will this blanking plate fit my patio door handle?
This blanking plate will fit any patio door handle with 154mm screw centres. While designed specifically for GreenteQ Alpha handles, it's compatible with most standard patio door configurations from various manufacturers. The plate measures 225mm in length and 32mm in width overall. Before ordering, check your existing backplate measurements against these dimensions using the technical diagram in the product gallery to ensure a perfect fit.

Do I need to change my cylinder if I'm blanking off the outside access?
Yes, this is crucial. If you're replacing an external pull handle with this blank plate (removing outside access completely), you must change from a full euro cylinder to a half cylinder. A full cylinder would protrude past the blanking plate as there's no cylinder hole on the plate itself. A half cylinder only operates from inside and sits flush behind the plate, with no external keyhole visible. This also enhances security by eliminating the external cylinder that could be vulnerable to attack.

Does this blanking plate come with screws or fixings?
No, fixings are not included with this blanking plate. Most installations can reuse the existing screws from the old backplate, which saves waste and usually provides the correct length for your door thickness. If your existing screws are damaged, corroded, or missing, you'll need to purchase appropriate exterior-grade screws separately. Ensure any replacement screws are suitable for outdoor use to prevent rust and corrosion.

Can I use this on left or right-handed doors?
Yes, absolutely. This blanking plate features a universal reversible design that works on both left and right-handed door configurations without any modification. Simply position it over your screw holes regardless of door handing, and it will provide a professional finish. This eliminates the need to specify handing when ordering, making it a truly versatile solution.

What's the difference between this and the internal backplate?
This is an external blanking plate designed for the outside of your patio door. It's manufactured from zinc alloy to withstand weather exposure, UV light, and outdoor conditions. The internal backplate (if you have one) would typically include a handle mechanism and would be on the inside of the door. This external blanking plate is used when you want to eliminate outside access completely whilst maintaining full internal operation of your sliding patio door.

Which colour finish should I choose?
Choose the finish that matches your existing internal patio door handle for a cohesive look. Polished Chrome offers a bright, mirror-like reflective finish that's traditional and elegant. Satin Chrome provides a contemporary soft sheen that hides fingerprints better and suits modern aesthetics. White is ideal for matching white uPVC door frames and creates a seamless, subtle appearance. Black delivers a bold, modern statement finish that's increasingly popular in contemporary home design. All finishes feature the same durable zinc alloy construction with corrosion resistance.
