How much is fire hydrant glass? Who can talk about it?

Hello, measure the length and width (pay attention to the frame from the inside) and go to the glass shop to cut a piece. Three thick glasses. Install it. Around 20 yuan. Then go to the fire equipment store to buy a fire extinguisher and mark the purpose. Just two or three yuan.

If it is conventional fire hydrant glass, it is also sold in fire equipment stores, but the price will be slightly more expensive.
