The Whitco MKII Tasman security screen door lock has been securing houses for years. This is an exact replacement for the Tasman.

This lock will suit most hinged security screen doors. They will replace most other brands also. 

Featuring the new, non sag handle design, and internal snib for convenient locking this lock will give years of service. This kit has everything in it to set up your door except the lock cylinder, which you can usually use from your old lock. If not, they are also available in my store from $15.
