Bondor's Model BR1010
Bondor Inflatable Rail Seals' "all rectangular" design eliminates cropping of corners providing full access to door opening
width.  Two basic models offer maximum flexibility in sealing a variety of railside dock conditions. A 3-sided inflatable may
be used where a loading dock protrudes from the building face. Bondor 4-sided, inflatable rail seals provide the finest
railcar to building seal. Pressure against the railcar on all 4 sides assures a constant gasketing effect minimizing heat or refrigeration loss. Material is 18 ounce vinyl coated nylon. Shock cords are provided to help eliminate sag of deflated seal.
Each rail seal includes a standard blower with a heavy duty 1/3 h.p., 115 volt, single phase blower with a die case aluminum
housing. Electric control switch by others. A galvanized weathershield is provided for protection if blower is to be externally
mounted.
BR 4-SIDED RAIL SEAL

TO ORDER A SERIES BR1010/4 RAIL SEAL:

1. Measure the distance from the building face to the centerline of the nearest rail. (Dimension X in the sketch below).
Also measure the building wall setback from the edge of the rail dock (Dimension Y in the sketch below).
2.

Determine the required rail seal projection by adding dimension X plus dimension Y minus 24".  
Example:  X + Y - 24 = rail seal projection.
Dimension      X  =   72" to centerline of track.
Dimension   + Y  =    0" no setback of building wall.
               Minus     - 24"
Required Projection 48" Dimension Z

3. Verify the rail seal design preferred; either a 3-sided series BR1010/3 or 4-sided series BR1010/4
Rail Car Seal Selection guidelines:
* 3-sided seal provides shelter from weather and safety to employees. 3-sided seals are usually selected where there
is a building setback "Y" or where conservation of heated or refrigerated air is not an issue of paramount importance.
* 4-sided seals provide shelter from weather and safety to employees as well as closing the air gap beneath rail board.
The fourth (bottom) segment will reduce heated or refrigerated air loss. A 4-sided seal also provides additional
security and insect control.
* Note:  If a three sided rail seal is required exit this page (go back two pages) to the Rail Seal section photos and
click on the 3-sided rail seal photo or link.
4. Enter the 4-sided (Price Table A) below to select the appropriate rail seal model number and price using the correct
rail seal projection "Z" and the corresponding door width X door height.
Example:  A 4-sided rail seal from Table A with a 48" projection "Z", a door width of 10', and a door height of 12'
would be a Model number BR1010/4/P48/10W x 12H at a price of $2,146.00
5. We invite you to let our engineers review your rail seal application. Complete the rail seal dimension sheet on our
contact page and we will confirm your rail seal selection.
