Just got me new HPS,and i need a little help with something!

ok so i got my new HPS from Fedex today,flawless HPS,looks great,400 Watts,everything is fine,except the top theres 2 holes to use to hang it from something and i got nothing to use to put in the holes to hold it up.

What would be good for this,i need like a VERY strong string to use,i got a dog leash that fits the one hole but i dont got another one so i cant use it for both holes.Any strong enough wire or strings anyone can think about?I got fishing line but i dont think itd be sturdy enough,any help would be appreciated

get small chains and hooks, secure it well you don't want it falling down and breaking, probably breaking plants at the same time

Thanks,yea i def dont want it falling down it would be terrible.ITs a nice hps i plugged it in and its bright as hell lol.

These are great and cheap too i use em all the time and support 34kg/75lbs each
