Happybuy Door Push Bar Panic Exit Device with Dogging Key and Exterior Lever Commercial Emergency Exit Bar Panic Exit Device for Wood Metal Door Panic Exit Bar (Push bar with Dogging Key)

The product is satisfactory, but the supplier has failed to respond to my request for information and help. The keys are not available to be reproduced in my area make the product only half useful. Plus I asked for replacement locks keyed alike and no reply. I am willing to pay for keys and locks, l really need them for the panic bars to work properly in my situation.

1 set I had the problem after installed- emailed and they were very quick sent me another set- installed second set but the locking mechanism itself have had the same problem- I have had problem in closing and opening the door. Sometime it open, sometime unable to open. The closing is a problem. Will not buy it again
