Product Description

Coated Polycarbonate Door for Cat C- and D-Series Loaders

Replace the original Cat door glass with a clear, formed polycarbonate panel built for the existing cab door. Choose the machine series and thickness that match your application, then confirm the OEM glass number before ordering.

Choose the correct door

  • Cat C Series: replaces OEM glass 258-4071
  • Cat D Series: replaces OEM glass 345-6230
  • Thickness options: 1/4, 3/8, or 1/2 inch

Some Cat sub-models use a serial-number break. Do not choose by model name alone. Confirm the glass number through a Cat dealer when the number is not visible on the original panel or in the machine parts record.

Listed machine families

The C-Series option is listed for select 246C, 256C, 262C/C2, 272C, 277C/C2, 279C/C2, 287C/C2, 289C/C2, 297C, 299C, and related configurations that use 258-4071.

The D-Series option is listed for select 226D through 299D loaders, including D2 and D3 updates and certain XHP, XE, and R configurations that use 345-6230. The OEM number remains the controlling fitment check.

What the panel is built to do

  • Matches the shape and mounting-hole pattern of the specified OEM glass
  • Coated on both sides to improve abrasion resistance
  • Available in three thicknesses for different operating needs
  • Accepts the existing OEM seal and door hardware

This listing is for the polycarbonate panel only. Hinges, latch, handle, seal, wiper parts, and mounting hardware are not included. Moving from thin factory glass to 1/2-inch polycarbonate may require longer fasteners.

Before you order

  1. Match the machine and series.
  2. Confirm OEM glass 258-4071 or 345-6230.
  3. Select the intended thickness.
  4. Inspect the reusable hardware and seal.
  5. Ask SSC to confirm current production time.

Will this fit every Cat C- or D-Series loader?
No. Serial breaks and cab configurations can change the door. The matching OEM number is the safest way to select this panel.

Does it include a complete door frame?
No. This is a replacement panel for a machine that already has the applicable OEM door and reusable hardware.

Which thickness should I choose?
Choose the thickness required for your work and existing hardware. A thicker panel can require different fasteners; it does not change the fitment requirement.

Need help checking the part? Contact SSC with the machine model, serial number, OEM glass number, and photos of the door opening and hardware.

Confirm fitment before ordering

A machine model listed on this page does not, by itself, guarantee fitment. Before ordering, use your machine serial number to confirm the required OEM part number through the manufacturer or dealer, the applicable owner's or parts manual, or an authoritative OEM parts catalog. Match that OEM number and the existing door or window configuration to this listing.

If SSC correctly ships the item, SKU, and variant you selected, but the selection is not correct for your machine, the order is not eligible for return, exchange, refund, or credit, and SSC will not cover any costs to correct the selection. If SSC ships a different item than you ordered, we will make it right at our expense.

If you are uncertain, contact SSC before ordering with the machine make, model, serial number, current OEM part number if available, and clear photos. Review our Returns and Refunds Policy.

Questions & Answers

Have a Question?

Ask a Question
  • Will this fit a cat 226?

    CAT 226 loaders span more than one model series. This panel fits only when the existing OEM door glass is 258-4071 (C Series) or 345-6230 (D Series). Confirm the OEM number from the machine serial number before ordering, then choose the matching series and thickness. This listing is the replacement panel only; hardware and seal are not included.

  • Will this fit a 289D

    A Cat 289D uses the D-Series option when its existing OEM door glass is 345-6230. Some sub-models have serial-number breaks, so confirm the OEM number before ordering. Choose the required 1/4-, 3/8-, or 1/2-inch thickness. Hardware and seal are not included.
