Instructions for Inserting Plugs

• Step 1 – Align plug so that it sits evenly atop the slot that it will be pressed into
• Step 2 – Gently push with both thumbs, alternating from the top to the bottom, and repeat. This will slowly work the plug into position in a small amount at a time. (If you try to force the plug in, it will tend to stick, and will then require more effort than necessary. It may help to get the sides of the plugs wet so that they slip in more easily)
• Step 3 – Once the plugs are in place, it may take a couple of clamping cycles on the bar to get them completely seated. This entire process should only take a few minutes for each collar

The standard rubber plugs included with these OSO collars are gray, but customers can opt to add a 4-pack of extra rubber plugs to their order in any one of a dozen additional colors. Check them out here.
