Sprinkler riser assembly

A sprinkler riser assembly comprising:

• a stabilizer base defining a generally planar top surface;
• a riser mount and coupler, removably mountable onto said stabilizer base above said generally planar top surface;
• at least one manually operable removably engageable hook removably attachable to said riser mount and coupler, said at least one manually operable removably engageable hook comprising at least one manually operable removably engageable hook pin-receiving hole;
• and
• at least one pin, including a head portion and a shank portion,
• said stabilizer base including:
• at least one pressure mount portion;
• and
• at least one stabilizer base snap engagement portion,
• said riser mount and coupler including:
• a generally planar slidable portion for connecting to the at least one pressure mount portion of said stabilizer base by sliding over a portion of said generally planar top surface of said stabilizer base,
• at least one riser mount and coupler snap engagement portion for operative removable snap fit engagement with said at least one stabilizer base snap engagement portion;
• and
• at least one first lateral rib, including a first rib pin-receiving hole formed therein, and at least one second lateral rib, including a second rib pin-receiving hole formed therein, said first and second lateral rib pin-receiving holes being generally mutually aligned, and
• said shank portion of said at least one pin including:
• an upper segment, adjacent said head portion,
• a first tapered region, adjacent said upper segment;
• a first intermediate segment, adjacent said first tapered region;
• a second tapered segment, adjacent said first intermediate segment;
• a second intermediate segment, adjacent said second tapered segment;
• a third tapered segment, adjacent said second intermediate segment;
• a bottom segment, adjacent said third tapered segment;
• and
• a fourth tapered segment, adjacent said bottom segment,
• said manually operable removably engageable hook being attachable to said at least first and second lateral ribs by insertion of said at least one pin through said manually operable removably engageable hook and said first and second rib pin-receiving holes,
• said first rib pin-receiving hole having a diameter permitting unimpeded passage of said shank portion therethrough;
• and
• said second rib pin-receiving hole having a diameter less than the diameter of said first rib pin-receiving hole, thereby causing said second intermediate segment of said shank portion, upon insertion of said at least one pin through said first rib pin-receiving hole, to rest on an entrance of said second rib pin-receiving hole.
