CLIP SIZE

Knockoff works with fiber cement siding in widths up to 5/16 of an inch.

CLIP LENGTH

The 1-1/4" length guarantees every piece of siding is consistently and accurately aligned each and every time. There is NO NEED TO SNAP CHALK LINES for every row.

PRODUCT COMPOSITION

Knockoff is made of durable, lightweight, recyclable plastic. It took nearly one year to find the correct mixture of plastic that would allow the product to break each and every time -- regardless of weather conditions.

SEPARATION POINT

This is a critical feature. The separation point is designed to break so that the remaining piece does not prevent the two pieces of siding from being installed against each other.
