SuteckPlumbing Access Panel for Drywall Ceiling 14 x 29 Inch Reinforced Plastic Wall Access Doors Removable Hinged White

Would this work for a laundry chute?

What type of adhesive would you recommend?

I accidentally separated the wall access panel into 2 pieces, how can I fix them together?

Hello, before installing the drywall access panel, does the cutting size refer to the overall panel size or the access door size?
