The Polly Table Hot Plate is our exclusive solution to a major problem for parks and campgrounds: accidental burns and melt damage on their picnic tables caused by hot pans or tabletop grills. Our Hot Plate provides a thick heat shield that won’t transfer heat to the surface below. Secure it to your table and it’s like a permanent trivet. This product is designed to be screwed directly onto rectangular tabletops whether made of 2 x 10’s or 2 x 6’s. One side is engraved to instruct guests about its purpose. The reverse side is smooth and unaltered. The heat shield can be installed with either side facing up. You’ve made an investment in your furnishings, so we’ll help you protect them. Available as an option to your table order, or independently to protect your existing tables. Includes: Pilot Holes, Security Screws & Specialty Bit for Installation
