How to Measure for your Arbor Lattice

Measuring Projection:
Measure the distance you want covered from your house to the end of the Rafters on the Arbor Lattice.  The Lattice Tubes will be set back a few inches from the end of the Rafters and the Beam & Posts will be generally set back about one (1) foot from the end of the Rafters.

Important - Fascia Attachments:
If you are attaching to your Fascia only measure the area that the awning will be covering.  Do not include the Eave/Fascia projection on your house, only measure from the point where the Awning will be attached to, Eave/Fascia attachments should be measured from the outside of the Fascia board.

For example: You want to attach to your Eave/Fascia of your house and have a 10' slab coming from the wall and you want to cover the entire 10' of slab.  To measure properly you would measure from the outside of your fascia board to the end of the slab.  Say you measured your Eave/Fascia projection and came up with 2' in projection.  You will want to order an awning with an 8' projection to obtain a total distance away from the wall (not Fascia) of 10'.


Measuring Length:
Measure the distance you want covered along your house, this is the distance the Lattice Tubes run, the Rafters will be set back from the end of the Lattice Tubes generally about one (1) foot.  The Posts will be generally set back about one (1) foot from the end of the covered area under the Beam, Post spacing will vary depending on Snow Load, Projection and Height.  You will need to fill out a Free Quote to have the details figured on your particular application.


Posts & Slab - how close can I come to the edge?:
The posts are required to sit back at least 4 inches from the edge of your concrete slab (what if I don't have a slab?) to allow for expansion by the post bracket anchors, if the anchors are less than 4 inches away from the slab the concrete may become weakened and crack; so just make sure you measure at least 4 inches back and you will be fine.

The posts will sit back generally about one foot from the end of the awning which means it can cantilever past your slab allowing a larger cover to be installed, this is important in situations where small slabs are in place and you may want a slightly larger size cover than your existing slab.

MEASURING EAVES/FASCIA

If you are thinking about attaching to your eave/fascia you will need to make sure your eave/fascia can handle the load your awning will add.  The Arbor Lattice Engineering has specifications for eave attachments, you will need to measure the size of your rafters (i.e. 2" x 4", 2" x 6", etc.) the spacing of the rafters (i.e. 16", 24", etc.) and how far the fascia board is from the wall (eave projection).  Also, you will need to attach an A34 Clip (90 Deg. Clip) to the back side of your fascia board and the rafter to create a mechanical connection so the fascia does not get pulled off the rafters.  If you have a closed soffit you will have to access the bottom of your eave or attach to the wall instead.
 

1) Rafter Spacing on Center: 
Measure from the outside of one rafter to the inside of the next rafter to get your spacing on center; usually rafters are spaced every 16 or 24 inches.

2) Rafter Size:
Measure the width and height of your rafter, usually rafters are either 2" x 4" or 2" x 6".

3) Eave Projection:
This is the distance out from the wall to the outside of the fascia board.  When you measure this do not follow the angle of the rafter, you will want to measure straight out from the wall using a level.

Note: When attaching to the fascia you will need to place a 90 Degree clip from the rafter to the fascia board.  This clip is commonly known as an A-34 clip, you will have to purchase this locally for very little expense at any Home Center.  This may be a problem for you if you have a closed soffit, you have to be able to get into the back side of your fascia to install this clip or you will not be able to meet engineering and obtain a permit.
