The CRL Model Number VW1033 is a Sliding Style Van Bunk Window ( Slider , Half-Slider) that can be installed on virtually any Year, Make Model of Van. While bunk windows are generally installed in the upper rear quadrant of a Van, this is not a required placement of the window. Due to the windows universal fit nature of the window you can place it in any position of the Van which benefits your usage. Since this window is a Sliding type it does feature track drainages so when installing you will need to make sure the diver and passenger sides go to the corresponding side fo your van. The outer dimensions of the window is 33-7/8" x 10-7/8" and the hole you will need to cut in the wall is 33" x 10" . Best practice is to keep the window within a single sheet metal section of your van wall as multi-depth walls will require much more labor to correctly install. Also always keep in mind that the Bunk Window is Flat and does not make allowances for Van walls curvature.
CRL (CR Laurence) utilizes its popular Clamp Ring installation method for this Half-Slider Bunk Window, Clamp Ring originally developed in the 1970s, utilizes a factory aluminum frame as the main structural frame of the window. The main frame of the VW1033L/VW1033R is 33 inches wide and 10 inches tall. The mechanism and glass are integrated into the main structure.
To seal your VW1033 Series Slider Van Bunk Window, an EPDM rubber seal is pre-applied to the aluminum frame. This seal, once the window is installed, will be compressed against the outer wall of the van creating a weather-tight seal. Also to help with water dissipation is the drainage slots or weep holes. Water that enters the sliders track then is directed out of the slots and back out of the exterior of the van.
The bunk windows slider opens to approximately 13-9/16"x 8-3/16" this provides great ventilation for a small window and slider windows are always the best options for ventilation while driving. These Half-Slider Windows have an interior rubber channel which holds the glass and is designed to reduce moisture and air from entering the cabin of your Van. Since the sliding glass has to allow for movement of the panel slight water entry when raining or a high-pressure hose, also under extreme wind conditions, slight air noise can occur. While I can understand the though of water entering can seem alarming that is what the drainages are for and there should be nothing to worry about.
The Interior Bug Screen measures 15" x 9" has a black coated frame which encapsulates a fiberglass mesh screen.
The VW1033 Series Sliding Bunk Window from CRL can be removed rather easily to movable clips are on the outside frame and the frame of the screen slides into a channel in the center, a turn of each slip then pull screen out of center channel and you can now clean the glass of your window , repair or replace your screen or simply have a screen-less opening. The screen is also repairable and much lick a home screen has a rubber gasket which is embedded into a channel and holds the screen mesh. Utilizing a screen repair kit you can always fix on your own and avoid the cost of a full replacement.
Located in the Center / Center of the window you will find the sliding windows latch a squeeze style clip latch you simply squeeze the clip to release and use as a handle to move the glass open or closed.
Since Bunk Windows are universal you will need to create your own template. You can do this one of two ways. Easy way Tape the Trim Ring together. Place on a piece of cardboard (Perhaps the window box) trace to the inside of the ring that touches the cardboard. While this is easier it is also less accurate. Measuring the trim ring we used to produce this information it measured 33-3/16" x 10-1/8" both measurements being slightly larger then the 33" x 10" that the actual frame of the window is. You will want to make sure to always cut to the inside of the line you created to compensate. A more accurate way would be laying the window itself outside glass side up on the cardboard mark the handle (you will notch a rectangle for the handle to fall in approx. 2-3/4" x 1" so the frame of the window is flat to the cardboard then trace off of that. This will be more accurate to the frame of your window having less play in the hole leaves more tolerance for unintentional over cutting of wall.
The Clamp Ring or Trim ring of the window is attached to the main frame of the CRL VW1033L and VW1033R Slider Bunk windows from the interior side. When the hole is cut in the wall, the main frame of the window extends to the interior (about 1") from the outside. The clamp ring caps over the main frame are attached by #8 x 3/4" black pan-head screws. The basic idea is your van's sheet metal wall is sandwiched between the rubber seal and aluminum frame on the outside and the clamp ring on the inside. Since this window is flat always tighten screws very slowly few threads and on to next screw keep moving around the window until all screws are completely tightened and the ring is sitting tight against main frame with no gaps. The reason for the slow attachment is to finesse the wall and window together. Installing the bunk window to quickly can result in bucking of the van wall.
