 The adjustable top flap is optional during the use 

of the ramp. The top flap should NOT be used when it may 

interfere with opening and closing a door.

Align the end of the adjustable flap to the end of the highest 

ramp extension piece. Slide the flap through until the screw 

holes align.

Use one tapping screw to secure the flap to the ramp.

Step 1.

 Once assembled, take the ramp 

to the desired location and put the back 

flush against an elevated threshold.

Step 2.

 For permanent mounting, mark 

the surface below where the two holes 

are on the adjustable flap (optional) and 

the two holes are on the base of the 

ramp. Drill holes where marked.

Step 3.

 Use included flat head bolts for securing the ramp into place through the mounting holes 

shown above.

 After it’s determined where 

each piece will go, align the front of the ramp ex-

tension into the back of another extension piece 

and slide together until the screw holes match up.

Use one tapping screw to secure each ramp 

section together. Repeat until all extension pieces 

are secured to each other.
