Heeling & Toeing

Heeling and toeing a sash or door requires the glass to be blocked at the back bottom corner (hinge location) and the upper leading edge of both the opposite top and side. The glass then acts as a brace to prevent the hinged panel from dropping.

The Process

  1. Being a two-piece block, Piece One is first pinned to the rebate before the glass is installed.
  2. Once the glass is installed, Piece Two is pushed over Piece One.
  3. The two pieces lock together with ribs.

Benefits

  • A lip holds the glass to help prevent it falling when glazing vertically.
  • Piece Two locks over Piece One to prevent any sliding or dropping.
  • Is compatible with IGU polysulphide seal
  • A Dry System suitable for both factory and site glazing.
  • Eliminates guess work around the heel and toe process.
  • Fully supports the glass.
