Product Code: ELF1
Product Description
ELF1 & EL1
Standard device for single-leaf doors
This door interlock is the compact version of the DL(F)1. The device meets the essential quality features of the larger design, however with reduced type diversity.
The EL(F)1 is often used for the modernisation of lift installations, if no longer available door locks of other competitors have to be replaced.
If you are replacing an existing old type door lock then please quote the full code on the White sticker as per PFD Document (Kronenberg Identification Label). The lock often needs to be removed for this code to be visible. Please see picture above.
