This high quality Sleeve-style Letter plate is the best choice available to provide a full weather sealing, draught free environment.
Made to very exacting standards the quality of this letter plate is far ahead of most manufacturers. Designed for timber and composite doors, it is tested to 50,000 cycles and all finishes are tested to 480 hours salt spray. The flaps are sprung loaded and operate to 180 degrees - meaning they won't snap off, and can easily accommodate full A4 sized envelopes.
The design looks identical front and back and the heavy, solid construction and careful draught-proofing makes this item the best on the market.
To ensure maximum resistance to the weather, these letter plates should ideally be fitted to a new, purpose-cut aperture in the door. This ensures that the door has as tight a fit as possible around the sleeve to make it impervious to the weather. The item can be retrofitted to existing holes, however if the hole is too large or oddly sized, this can impact on its usually excellent weather-proofing.
For improved weather seal and acoustic resistance you can order the Rubber drip gasket separately.
Supplied as a set with interior and exterior flap, with all necessary fixings.
