    Good Product

  • Great
    Verified Buyer 08 February, 2016

    We have been wanting a more secure way to have various church members drop off money and checks for various groups/events/offerings. Putting this drop box inside a locked room provides double security and an easy way for people to leave it in a safe place. The one thing I would recommend is to leave more space for a little larger envelopes to go in and drop down, which tend to stick.

    Verified Buyer 17 November, 2014

    The slot is a little to small for some checks and you really have to make sure they "drop" into the box.

  • drop box

  • Great deal, well built
    Verified Buyer 16 March, 2012

    Well built an easy to install. Could use a sealing system but still a good buy.

  • What thickness doors will this work on?
    From Tom at 9/8/2015 1:18 PM
    Hello Tom,
    • Fits in a door up to 2" thick.
  • can this be mounted on a wall as well as door?
    From Anitra at 6/14/2017 9:23 AM
    Hello Anitra,
    • This is meant for doors up to 1-3/4" thick. Unless you have a wall that is 1-3/4" thick and made of solid material, then the unit will not work.

      For a through-wall drop box, we recommend the Protex WDC-160.
