    Will it work with slack adjusters with a square head nut?


    I hope this will help, the 4651 works on 5/16" square.


    I bought some a while ago but the wrenching one is jump at time does it have a warranty?


    I believe Lang tools have a lifetime warranty.


    Is it possible to use them on systems that are not meritor?


    They work on multiple different types.


    Are the gear teeth exposed or are the wrench enclosed?


    There are gears exposed around the top and sides. It still works well more than a year later.


    Are they still shipping during the outbreak?


    We are shipping, order today and we will ship tomorrow.
