I want to make a instruction for vertical ladder installation (Securing a ladder to a wall firmly with screws or something) Information I want to put in the sentence is:
Secure one spot (less than 0.5m from the floor) of the ladder to the wall
the rest of the part: every 1m
I don't know how to put these into a sentence...
- "Secure at least 0.5m from the floor and every 1m of the ladder to the fixture."
- "Secure one spot within 0.5m from the floor and every 1m of the ladder."
please help me. thank you.
