Lockwood Onyx Universal Strike Packer 3mm - Black - 9A-141BLK
The Lockwood Onyx Universal Strike Packer 3mm - Black is an accessory component for the Lockwood Onyx sliding door hardware platform. It is used behind a compatible Onyx universal strike to help adjust projection and alignment where additional spacing is required.
This 3mm packer is supplied in a black finish to coordinate with black Onyx strike hardware. It is suited to sliding door applications where frame conditions or installation tolerances require the universal strike position to be built out.
It is intended for use as a strike packer rather than as a standalone locking component, so it should be selected together with the correct compatible Onyx universal strike.
