Security Fence Expansion Pack - Expansion pack for the security fence model without the barbed wire on the top This expansion pack currently has 3 models that can go along with the valve security_fence_section_01.mdl model. There is currently a pole, quarter sized fence, and full sized fence without end poles which allows for infinite fences in theory. This is a valve model edit so credit is not required but appreciated. TO INSTALL: Unzip folder containing models folder. Drop models folder into the tf folder. Done.
