                  Installation instructions  

  In-ceiling SandTrap          

Installation:
Sand-fill each quartered hull via the sand fill-hole.

Use clean dry sand. Avoid beach sand.
Each quartered hull installs through the speaker drywall cutout.
The SandTrap accommodates a typical 6.5" to 8" custom in-ceiling speaker.

Trim a funnel to sit on the inner-ledge of the sand-fill hole.
This minimizes insertion depth which provides easier flow.

Recommended Funnel

PT Performance # W54275
This recommended funnel does not require any modification.

Available at local auto parts stores & amazon. 

Stand the SandTrap near vertical.
Then scoop and shake to fill a pair in about 10 minutes.
Seal hole with glue & supplied plug.

Insert each quartered sand-fillled hull through the custom speaker cut-out.

Use an adhesive such as poster putty to hold in place.
We recommend a stronger adhesive
such as 3M Strip Calk for a steep vaulted ceiling installation.
Insert and clamp the speaker to the SandTrap inner-clamp-rim. 

We have provided a "string hole" in each hull.
Insert string or fishing line through the hole to
allow the retrieval of a hull accidentally dropped in a vaulted ceiling.
