Hey Guys,
I have a Whitco branded Euro style double cylinder on my screen door which I have wanted to replace with a Mul-T-Lock MT5+ Euro cylinder but I have just found out that the Whitco cylinder is a bit unique.
A few points about the Whitco cylinder.
*The cam on the Whitco cylinder will only move for about 170 odd degrees of rotation (straight down to almost straight up).
*The key will turn about 340 degrees from stop to stop.
*The cam is a Floating/Lazy cam as I have found out, seems to be very popular for the Whitco locks here in Australia.
*The cam can be moved about 170 odd degrees without the key inserted.
I have a CISA Euro cylinder that has a 'locked cam' (cam is locked to the key plug in its entire rotation) that I have tried to install.
I believe most Euro cylinders are like this.
The door will lock and I am able to remove the key, However, when I unlock the door I am unable to remove the key as the plug has not returned to the 'home' position. Basically it acts like a key retaining lock.
The other issue with using a Euro cylinder with a locked cam is that I cannot use the internal locking lever as the cam on the cylinder is locked.
I have asked a few sellers about the Mul-T-Lock MT5+ Euro cylinders to see if they have locked cams and one said it is completely locked to the plug and another said there is about 90 degrees of free rotation.
From eyeballing the key position with the CISA cylinder is I need about 90-100 degrees of free rotation to be able to have the plug return 'home' so I can remove the key.
I was hoping if someone could please clear this up.
I would really like to use the MT5+ cylinder.
Thanks
