  • If you need to hire an expert, make sure that they know exactly what cap your gas lamp post needs!

How to Cap a Gas Lamp Post, you need to measure the height of the post and make sure there are at least two inches between where it meets the ground level. The top section should be threaded so that if someone bumps into it, they will not fall through or crack their head open on its metal surface.

You can use an old tire inner tube for this task because when wrapped tightly around the threads of one side, it creates enough room to thread them in without any space needed. Thread both sides with care before tying up all four ends together securely. If necessary due to age or size, add more layers until your safety is guaranteed!
