Don't use this company. Doesn't appear they vett their service people 4 experience or even knowledge. Rep wouldn't stop profusely sweating & wiping his face constantly with his shirt & arm! (disgusting and it wasn't even really warm outside or in my home.) He made excuses that his integrity was better than the product being installed & took all the hardware 2 get "better" 2 make the install stronger. The next day he never showed up & neither has my hardware. Company refuses verbal contact.
