Each quartered hull =
6 in. wide x 9.5 in. long x 1 in. deep.
The inner-rim clamping surface =
I in. wide x 1/4 in. deep
Accommodates a typical 6.5" to 8" architectural in-ceiling speaker.
Sand-fill each quartered hull via the sand fill-hole.
Use clean dry sand. Avoid beach sand.
Trim a funnel to sit on the inner-ledge
of the sand-fill hole.
This minimizes insertion depth which provides easier flow.
Performance # W54275 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
Use an adhesive such as poster putty to hold in place.
We recommend a stronger adhesive (3M Strip Calk) for a 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.
This allows the retrieval of a hull accidentally dropped in a vaulted ceiling.
