Adjustable Aluminum Top Sills

Adjustable up to 1/4" to compensate for uneven door bottoms and sub-sill level changes.
  • Two-part zinc plated steel stud shoulder screw joins a long-barreled, zinc plated steel T-nut for superior stability and long-lasting reliability.
  • PemkoPrene moisture barrier prevents water intrusion. Design of PemkoPrene® bulb configuration keeps constant pressure between aluminum cap and aluminum extrusion at any level of adjustment.
  • Sills can also be ordered with a narrow trim piece by adding "NT" to the end of the product number (i.e. 94518A36.5NT).
