LAY OUT THE BUILDING SITE

After the site is prepared, identify the location of the shelter corners to help

square the frame during and after assembly.

Taking these steps before assembling the shelter saves time and ensures that

the structure is positioned as desired. The following procedure is a suggested

method. Its use depends on the size of the shelter, shelter application, the

footings, and the method used to anchor the shelter.

SQUARE THE SITE

Identify a corner where a building rafter will be positioned, drive in a stake,

and string a line the exact width of the building and stake in place. (Width of

the rafter is measured from center-to-center of the rafter legs.)

String a line at least as long as the building from the first stake at 90°.

NOTE: A transit can be used to ensure an accurate 90° angle, or the 3-4-5

rule can be used. Refer to diagram. Using multiples of 3-4-5 such as 6-8-10

or 12-16-20 helps to maintain an accurate 90° angle.

After squaring the position of the building and placing a stake at all corners,

string a line between the stakes to mark the base of the building.

Next, mark a line on the ground using the strings between the stakes as

guides. The string line can also be used to align rafters during assembly.

NOTE: There is no need to mark the rafter spacing. The purlins, when

installed correctly, will maintain even rafter spacing throughout the length of

the shelter.

SPECIAL NOTE: Baseboards for Frame

Installing a baseboard under the mounting feet along each side of the frame is

recommended. The baseboard runs from the front to the back of the building.

This baseboard is not included with the shipment and must be supplied by the

customer. Treated or recycled plastic lumber works well for a baseboard.

The baseboard, when installed properly, helps prevent the shelter from sinking

into the ground when anchored. Baseboards also provide a surface to attach

rafter feet or other building components.

BASIC ASSEMBLY STEPS

Follow these basic steps to assemble your building:

Consult the diagrams within this manual to assemble your building. Note

that the two (2) end rafters are different from the remaining interior/mid

rafters. Consult the Connections and Connections Details diagrams. Brace

the first end rafter in place after setting it in position on the site. Do not

remove the end rafter bracing until interior rafters are set and attached

forming the frame.

Assemble the entire frame and anchor to the site.

Assemble, install, and tighten the cables.

Check all connections and install the ratchets for the main cover. Attach all

ratchets to the frame using Tek screws.

QH1065 Ratchets (large): All side positions.

QH1061 Ratchets (small): End rafter positions only. See Cover

installation steps for clarification and position. Use the QH1061

ratchets to secure bonnet of cover.

Install the main cover and tighten.
