Engineering Specifications
Click on image for enlarged picture.		• Heavy cast — made of aircraft quality 356 aluminum alloy • Heat treated to T6 conditions • Frames are machined with precision CNC equipment providing excellent dimensional tolerances • Yield strength equals 30 KSI! • Frame thickness equals 3/4" • The two frames are connected with 3/8"- 16 threaded steel rods and 1/2" OD aluminum spacers

IMPACT PLATES (Stop Plates)
	Machined from 3/8" x 2" solid 6061 T6 aluminum bar stock•Anodized•The 6", 12", 18" impact plates are connected with same size support bars•The bars have end support spring loaded ball plungers or brass tipped set screws•Impact plate squareness may be adjusted by correcting the distance between support bar and the impact plate
SLIDING
	The linear motion of the Posi-Stop is guided by 5/16"-18 x 3/4" L. teflon tipped brass set screws located vertically in the C-Frames•The screws slide on the top edge of the Guide Rail with very low coefficient of friction•They also provide simple square and height adjustment
LOCKING
	Locking mechanism components: Adjustable metal handle with special 3/8"-16 hardened steel stud•Replaceable 3/4" DIA steel swivel shoe•5/8" DIA x 4" long tool steel round with 3/8"-16 threaded hole•The handle locks with one-half turn (C-clamp action)•Single lock average capacity= 420 lbs. (static)•Double lock average capacity= 800 lbs. (static) •When the handle is in open position, the Posi-Stop can be removed from the Guide Rail at any location
READ-OUT
	Components: 1/8" x 1/2" x 1 3/4" lexan hair line indicator•1/2" DIA x 4" long precision ground and hardened steel shaft•1/2" ID shaft collars•Set screws•The indicator is attached to the bottom of the shaft collar which can be moved 1" to the left or right, for fine stop calibration
FLIP-UP MECHANISM
	Components: Two 3/4" x 3" x 3 1/2" heavy aluminum flip-up arms•1/2" OD and 3/8" ID oil impregnated sleeve and flanged bronze bearings•The flanged bearings are located in the C-Frame holes (press fit) providing smooth, free of backlash flip-up motion
UP-SLIDE MECHANISM
	Components: 1/4" x 1" x 2 1/8" special shape impact plate machined from grade C-1018 ground flat stock•1/2" DIA x 4" L precision ground tool steel shaft•Two 1/2" ID clamp-on steel shaft collars•Set screws•The impact plate slides up when it is pushed by the work piece and slides down (gravity action) when the work piece is removed
SWING MECHANISM
	Components: 1/4" x 1" x 1 5/8" special shape impact plate machined from grade C-1018 ground flat stock•1 1/4"x1 1/4" x 2" stop block machined from solid 6061-T6 aluminum bar stock•1/4-20 T-slot nuts, screws, and pins•The impact plate swings into the block when it is pushed by the work piece and swings out of the block (gravity action) when the work piece is removed
POSI-STOP SET-UP
	Unlock Time + Slide Time + Locate Time + Lock Time = 3 to 5 seconds (approximate)
