Flat Post Cap pvc whelping box

Deqing Huazhijie Railing & Fencing Co.,Ltd. manufactures the Flat Post Cap PVC Whelping Box at our facility in Huzhou, Zhejiang, near Shanghai, where we have produced PVC fence and PVC profile products since 2003. The box belongs to our PVC Pet Fence range and shares the lead-free virgin PVC formulation, extrusion tooling and hourly inspection routine used across our picket, privacy, pool and horse fence lines. Breeders, kennel operators, pet product distributors and OEM buyers use it as a washable, non-absorbent whelping enclosure that assembles from pre-routed components without carpentry.

As a China-based PVC whelping box manufacturer, we supply the box as a complete knock-down kit — posts, flat caps, post feet, pre-routed rails and the round pig rail — packed in cartons for direct resale or kennel installation. Buyers sourcing a custom Flat Post Cap pvc whelping box suppliers configuration can specify footprint, post height and rail layout against the standard platform described below.

A Whelping Enclosure Built Around the Dam and the Litter

The unit is a four-post enclosure with solid PVC walls rather than a fabric pen or a wooden whelping box. Every surface is non-porous, so fluids, bedding residue and disinfectant do not soak into the material, and the frame can be rinsed and wiped down between litters instead of being replaced.

• 100% virgin PVC throughout — no recycled content and no lead-based stabilisers in the formulation
• White finish that keeps the interior bright and makes soiling immediately visible
• Waterproof, non-absorbent walls that tolerate routine kennel cleaning agents
• Flat post caps close the post tops for a seamless finish; post feet raise the frame and add stability on hard floors
• Pre-routed rails with a round pig rail running the inner perimeter

Standard Sizes and Breed Matching

Three square footprints are produced as standard, all at 18.9 in overall height. The footprint is the first decision because it sets how much room the dam has to lie clear of the litter and how much floor space the whelping room must give up.

Component Specifications

Every kit is built from the same component set, so replacement parts and additional units stay interchangeable across repeat orders.

Assembly, Placement and Cleaning

The box arrives as flat components and assembles by hand. Rails are pre-routed at the factory, so they drop into the post routs and the flat caps and feet push on last — no cutting, drilling or fastening on site.

• Place on a level, hard, washable floor; the post feet keep the rail bottom clear of standing moisture
• Leave clearance on all four sides for the dam to enter and for staff to reach the litter
• Clean with warm water and a mild detergent, then rinse; avoid abrasive pads that dull the surface
• Check the pig rail and rail-to-post joints after each litter and reseat any component that has been lifted

Material Traceability, Extrusion and Quality Control

Profiles are produced on our own extrusion lines, then cut, drilled, notched, packed and stored in sequence under one roof. Raw materials are traceable, and an independent quality-control group inspects each extruder's output every hour in addition to random sampling.

• Lead-free, environmentally friendly PVC formulation with UV stabilisation for long-term colour retention
• Company-held certificates include CE, ROHS and UL94, alongside SGS, ASTM, ISO 9001:2000 and TUV global manufacturer certification
• Components are checked for rout position, wall thickness and cap fit before cartoning
• Production runs are held to the approved sample, so a repeat order matches the first shipment

Customization, OEM and ODM Scope

The standard platform is deliberately modular. Post height, footprint and rail layout can be adjusted for a specific breed programme or a distributor's catalogue, and we welcome OEM and ODM orders with customer branding and packaging.

• Non-standard footprints and post heights built to a confirmed drawing
• Playpen extensions and matching panel sections for post-weaning use
• Carton printing, label content and instruction sheets to the buyer's artwork
• New profile development supported by our in-house tooling and extrusion capacity

Information We Use to Configure Your Solution

A quotation is prepared from the working point rather than from a catalogue number alone. The following inputs let us confirm the size, post height, rail set and packaging in one pass.

• Breed, dam body length and expected litter size
• Required footprint and overall height, or the available floor area in the whelping room
• Number of units per order and whether repeat supply is planned
• Whether a playpen extension or additional panel sections are needed
• Carton marking, label language and any retail packaging requirement
• Destination port, shipping mode and required documentation

Packaging, Delivery and Documentation

Each whelping box is packed in a carton sized for the component set, which keeps freight volume low and lets distributors store kits flat until they are sold or installed. We confirm the packing list, carton dimensions and shipping marks with the order acknowledgement.

• Carton-packed knock-down kits with components grouped per unit
• Assembly instructions and an installation video supplied for end users and installers
• Export documentation prepared to the buyer's destination requirements
• Spare posts, caps, feet and rails available as separate line items

Frequently Asked Questions

What sizes does the Flat Post Cap PVC Whelping Box come in?

Three standard square footprints are produced: 37.4" × 37.4" × 18.9", 45.3" × 45.3" × 18.9" and 58.3" × 58.3" × 18.9". All three use the same 3" × 3" × 18.9" post and 7/8" × 6" pre-routed rail, so the choice is essentially a footprint decision. Non-standard sizes are built to a confirmed drawing.

What is the round pig rail and why does it matter?

The pig rail is a round profile running the inner perimeter of the box at a low height. It gives the dam a ledge to lean against instead of pressing her weight into the wall, and it creates a physical buffer that keeps newborn puppies from being trapped between the dam and the side of the enclosure. It is included as part of the pre-routed rail set.

Can the post height be changed for larger dams?

Yes. The 18.9" post is the standard height, and different heights are available. Taller posts are normally specified for large breeds where the dam needs more wall height to feel secure, or where the box will later be used as a weaning pen. We confirm the height against the dam's shoulder and body length before releasing the order to production.

Is the PVC safe for newborn puppies?

The box is made from 100% virgin PVC with no recycled content and no lead-based stabilisers, and the surfaces are non-porous and waterproof. That means bedding, fluids and disinfectant do not soak into the material, and the interior can be fully cleaned between litters rather than replaced. Our PVC formulations are produced under the same material controls used for our lead-free fence profiles.

How is the box shipped and how long does assembly take?

Each unit ships as a carton-packed knock-down kit with pre-routed rails, posts, flat caps, post feet and the pig rail. Assembly is a hand operation: rails drop into the post routs, then caps and feet push on. No cutting, drilling or fastening is required on site, and an installation video is supplied with the order.

Can you produce OEM or ODM whelping boxes with our own branding?

Yes. We accept OEM and ODM orders covering custom footprints, post heights, rail layouts, playpen extensions, carton printing and instruction sheets in the buyer's language. Send the target dimensions, quantity and packaging requirement, and we will return a configuration and quotation based on the working point rather than a generic catalogue item.
