Rollers & crescent locks

Sliding windows live or die on the rollers: the catalogue rates them per pair and prints the vertical adjustment range. Crescent locks are handed, so a two-panel window needs both.

Notes for this range

  • Roller loads are per pair, not per roller — a two-sash window uses two pairs.
  • The adjustment range is vertical, for levelling the sash after installation.
  • Crescent locks are handed; order left and right for a pair of sashes.

Used in these window systems

Single parts or a whole set

Distributors order by code and quantity; fabricators send the window and take the set. Both are quoted the same way.
