  • Smoked grey acrylic lens
  • Heavy duty aluminum base available in black powder coat finish
  • Quarter turn locking collet arm that allows for easy lid adjustments
  • True venting height dog position
  • Proprietary blended EPDM gasket system
  • High strength ergonomic dog handles with inside/outside opening feature
  • CE and ABYC compliant
Please note, this is an odd shaped hatch with one side measuring approximately 18" and the other approximately 15 5/8" overall. Please see the photos for additional measurements.  Trim ring not included.

Hello Lex,

Sorry - no screens of any kind are included. These came to just as is. You'd need to get the screens from Bomar.

I am looking for a 21"x21" escape hatch for the bow on my 1996 Bayliner Ciera 2355. Do you offer any. 757-218-7506

Hello Tim,
Unfortunately the largest size ventilation hatch that we have in stock is 18" at this time. We should have some more larger sizes in soon so be sure to check back.

Thank you and have a great day!
