FRAMEMASTER INTUMESCENT LETTERBOX

1 hour intumescent letterplates

1. Letterplate conforms to the requirement of BS/EN13724:2002
   
   
2. 180 degree opening on both sides means that flaps cannot be snapped easily when opening as the flap will be stopped by the face of the door or window profile
   
   
3. Internal water seal prevents water getting into the door or panel
   
   
4. water channels carry rain water away from the post and harmlessly down the sides of the letterplate
   
   
5. Brushes face the outside of the door for 3 very important reasons;
   
   a. Makes for better draught proofing
   b. It is easier for the postal service to post letters
   c. It stops vandals placing unwanted items i.e. fireworks, dog litter in the letterplate cavity.
   
   
6. Galvanised steel frame means the brushes won’t rust.
   
   
7. Blind bolts to the exterior prevents the outer frame being unscrewed from the door from the outside.
   
   
8. Scratch resistant surface means that attempts to deface the product using nails, or knives are virtually invisible
   
   
9. Ultra flexible springs means the letterplate will withstand thousands of openings without breaking
