Gebo deckhatch &
Flushline hatch
General description
The Gebo deckhatch and Flushline hatch are suitable as ventilation hatches. In the event of an accident or fire, the bigger sizes
can be used as an escape hatch. All deckhatches have been
designed for use on power and sailing yachts and can be used
in the toughest conditions. The Flushline hatch is especially designed for use on powerboats.
The GEBO deckhatch is Lloyds approved. All parts are made
from high corrosion resistant materials. When sailing on open
waters all hatches should be closed and secured.
Fitting & operating instructions
Fitting instructions
The hatch has to be installed on a flat surface with a maximum tolerance of 1 mm.
The deck must be sufficiently strong at the
installation point, if it is not, reinforcement
must be made.
Cut the hole in the deck according to
the aperture size of the hatch.
Make sure that the surface is completely flat and then place the hatch over the
hole. If the hatch does not fit exactly or
the surface is not flat adjust the hole.
If the lower frame is screwed down onto a
curved surface the sealing rubber between
upper and lower frames may not create a
watertight seal and the hatch will leak.
Place the hatch in the hole and drill the
fixing holes (drill diameter depending on
fixing screws).
Clean and degrease the mounting surface on the deck and the lowerframe for
the sealant (please note the specifications
of the sealant used).
Apply the sealant to the underside of
the lowerframe. Use a sealant, based on
butylrubber (not silicone or polyurethane,
as this may cause damage if the hatch is
removed in the future).
Place the hatch over the hole and
screw the frame to the deck using the correct torque (depending on fixing screws).
(If necessary) adjust the friction-hinges.
After opening and closing the Gebo hatch
several hundred times, it may be necessary to adjust the friction-hinges. Proceed as
Gebo deckhatch & Flushline hatch
Open the hatch to approx. 90°.
Remove the black end caps using a
small screwdriver. A small insert can be
found in the end caps.
Adjust the friction by using the supplied box-spanner. Tighten the selflocking
nut on both sides of the hinge turning
clockwise. It is adviseable to adjust all hinges fitted to the hatch.
10 After installation, remove the protective film from the acrylic.
N.B. Use only stainless steel fixing materials.

Operating of the hatch
After pushing the blue slide in the handle
outwards, the hatch can be opened by turning the handles. The hatch can now also
be opened from the outside (not the
Flushline hatch, external handle is an
By pushing the blue slide in the handle
inwards, the hatch is locked and burglar
(As an option, a stay is available for the
Flushline hatch as extra security against
the lid closing).
The friction-hinge will keep the lid open in
any position, thereby minimising the risk
of unwanted closing. For your safety is
important that the hinges are correctly
adjusted (see fitting instruction 7-9).
After long usage of the handle a spot of
water may drip from the handle.
If this occurs remove the blue slide (by
means of a paperclip or small srewdriver)
and tighten the self-tapping screw in the
handle, then refit the blue slide by pushing
it into the handle.
The durability of anodised or powder
coated aluminium has been proven over
many years. Altough aluminium is relatively maintenance free it is necessary to regularly clean the hatches. It is adviseable to
wash the hatches with lukewarm water.
The addition of a little soap solution will
assist the washing process, then wash
with clean water.
Never use:
• Alkaline products containing sodium
• Acid products like muriatic or those containing phosphor
• Steel wool, abrasives or sandpaper
• Cleaning-products for glass can also
contain alakline, which may corrode aluminium.
