YALE 1500 AND 2500 SERIES EXIT DEVICE CYLINDERS
Best currently supplies three different cylinders for the 1500 and 2500 Series Exit Devices.The use of the series
number alone does not provide sufficient information for determining which cylinder should be used on these Exit
Devices. the number of Trim being used must also be known as it is the only way of determining which cylinder
should be used.

Yale 1500 and 2500 Series Exit Devices, including 1500, 1501, 1502, 1510, 1511, 1520, 1521, 1522, 1531, 1532,
