Mason Company offers a high quality 'guillotine' type kennel door that allows for remote raising or lowering of a sliding polypropylene locking cover from outside a kennel run.

All cable, pulleys and necessary hardware is provided.  The 'with guard' door included an interior cable guard at extra cost.

The 'Max Flap' dimension indicates the maximum size opening the pet door will accommodate. They can cover smaller sizes.

Vertical sliding doors are ¹/₄” thick, low stress polypropylene. Channels are solid extruded aluminum 6063-T5. All doors have a 12” long galvanized steel chain extended by a ¹/₄” nylon cord, “S” hooks, pulleys, screw eyes and all necessary hardware for easy installation.

Available in three standard sizes: Regular - for openings up to 29” high by 12” wide. Large - for openings up to 29” high by 17” wide. Extra large - for openings up to 34” high by 17” wide. Other sizes available.

Ground Delivery Only.

Mason Company also offers the Pickwick 'Dog Operated Door'. This is a Very strongly built two-way pet door. The outside frame is  ⁵/₁₆" thick solid cast aluminum. The inside swinging door is  ¹/₄" thick polycarbonate. Spring hinges are plated to resist corrosion. 

These are primarily used in kennels and often in conjunction with the Kenl-Dor above. In that case, the Pickwick door provides for insulation and the Kenl-Dor is used to lock and unlock the opening.

The Min-Max dimensions specify a minimum and maximum opening that the pet door fits over. The entire assembly swings open when the pet is coming out. Only the inside polycarbonate panel swings inward when the pet goes back in.

No provision is made for locking (may be used in conjunction with the Kenl-Dor). Not recommended for cats. In fact, there have been cases where this door was used successfully to let the dog out while keeping the cat in! 

Noisy when closing.  Installation in a wall or hollow-core door requires framing. Requires a 2" minimum threshold.

Note: The manufacturer imposes a 10% restocking fee for all returned product which will be deducted from your refund.

Hot Tip: Outside frame dimensions do not include shims (which are included with the pet door).
