Help with Prop Lock

Is there a addon I can install to my server that similar to this thats not from the steam work shop?

Is there something wrong with the one on the workshop or are you trying to avoid using workshop?
If there's something wrong with the one on the workshop then I don't know what to tell ya because I don't know any alternatives.
If your trying to simply avoid using workshop you can use Gmad Extractor to pull the file from the workshop and then install it to your servers addons folder.
Link for Gmad: https://www.moddb.com/mods/garrys-mod/do...-extractor

on gmodstore you could probably create a job for a coder to custom make the addon for you if there is no commercially available product for what you want
