Glass Doors Owner Pls Help..

Hi

Need help from home owners who have installed glass doors at their home.

2 years ago, I have installed sliding glass door separating kitchen n living room. One panel is fixed while e other is not. E thing is, 2 days back e metal plate guide has dropped slightly showing e screw plugs which r supposed to hold it to e ceiling.

We only realised that red plastic screw plugs were used after e metal plate dropped. E door is for daily use n we thot something more durable should be used. We called our id consultant who is in a midst of fixing an appt with e supplier to get it fixed of coz with a price.

What I need to confirm is if e plastic screw plugs used for installing heavy glass doors e usual normal safe practice? Glass panels r heavy n being used daily, there are bound to be some wear n tear. But if plastic screw plugs will be used again to fix it, I'm sure e problem will recur n maybe worse, e whole thing will collapse.

So, anyone with glass doors have any suggestions or know what durable tools should to be used instead.

Thank you in advance.
