Product Overview

Finding the right way to wash taller, more delicate glassware can be a real headache. Standard dishwasher racks often leave your prized pint glasses, wine stems, or cocktail coupes dangerously exposed. This is where the Cambro CG979 36 compartment glass rack extender comes in, offering a brilliantly simple solution to a common kitchen problem. It’s designed to click securely onto your existing Cambro glass racks, instantly giving you the extra height and  protection you need.

Perfect for bustling pubs, high-end restaurants, hotels, and  event caterers, this extender is a must-have for any business that values its glassware. With 36 individual compartments, it ensures each glass stays put, preventing the costly chips and  breakages that happen when items knock together during a vigorous wash cycle. It’s a small addition that makes a huge difference to your daily operations, protecting your assets and  keeping your service sparkling.

Made from tough, chemical-resistant polypropylene, this extender is built to withstand the demanding environment of a commercial kitchen. By allowing you to customise your existing racks instead of buying entirely new ones, it’s not just a practical choice but a savvy financial one too. Stop risking your best glasses and  start washing them with the confidence they deserve.

Case Study: Real Business, Real Results

The Swan Inn in York recently refurbished their dining room and  invested in a new range of elegant, long-stemmed wine glasses. They quickly discovered their standard dishwasher racks were too short, leading to several breakages within the first week. They needed a fast and  effective solution that didn't involve replacing their entire rack system.

"The Cambro extenders were exactly what we needed. They clicked right onto our existing racks in minutes, and  we immediately stopped worrying about our new glasses. It’s such a simple idea, but it’s saved us a fortune in replacements already. The washing process is quicker and  safer."

Robert Green – General Manager, The Swan Inn

After installing the Cambro CG979 extenders, the inn reported a 95% reduction in glassware damage during the wash cycle, protecting their investment and  ensuring a flawless presentation for guests.

Installation and  Maintenance Guide

Setting It Up

  • Ensure both the extender and  your Cambro base rack are clean and  dry.
  • Carefully align the corners of the extender with the top of the base rack.
  • Press down firmly and  evenly on all sides until you hear and  feel it 'click' securely into place.
  • Give it a gentle tug to confirm it's locked – remember, this connection is permanent!

Keeping It Going

  • Rinse the rack after use to remove any large food debris before washing.
  • The polypropylene material is safe for all commercial-grade detergents and  rinse aids.
  • Periodically check for any stress marks or cracks, especially if handled roughly.
  • Stack racks upside down when not in use to allow for complete draining and  air drying.

Buying Guide: Choosing the Right Glass Racking

Not sure what you need to protect your precious glassware? Here are a few things to consider when building your warewashing system.

Measure Your Tallest Glass

Before you buy, measure your tallest piece of glassware from base to rim. Add at least 10-15mm of clearance to find your required total rack height.

Count Your Compartments

Match the number of compartments to your needs. A 36 compartment glass rack extender is great for standard glasses, while fewer, larger compartments are better for bulky tumblers or goblets.

Consider the Material

Polypropylene is the industry standard for a reason. It’s tough, lightweight, and  can handle the high temperatures and  harsh chemicals of commercial dishwashing day in, day out.

Check Your Dishwasher's Clearance

Make sure the final height of your base rack plus any extenders will actually fit inside your dishwasher. Measure the machine's internal height first!

Think in Systems

Using extenders and  racks from the same brand, like Cambro, is crucial. It guarantees a perfect, secure fit and  a stable, reliable system that works together seamlessly.

A: Not at all. It's a simple and  intuitive press-and-click system. Just remember that the connection is designed to be permanent.

Why a Permanent Fit Means a Safer Wash

You might wonder why the extender's fit is permanent. While it sounds a bit restrictive, it's actually a crucial safety feature. Think of it like this: you'd bolt a heavy shelf to a wall rather than just rest it on brackets, right? It's the same principle. Inside a powerful commercial dishwasher, water jets create a turbulent environment. A loose or shifting extender could easily detach mid-cycle, causing the entire stack of heavy, water-filled glasses to topple over. This would lead to widespread breakage and  a dangerous mess. The permanent clip-on design ensures the extender and  base rack become a single, solid unit, guaranteeing total stability and  keeping your glassware secure from start to finish.

Who Should Buy This?

  • Bustling Pubs & Bars: Ideal for protecting tall pint glasses, cocktail coupes, and  branded stemware during high-volume washing.
  • Hotels & Conference Centres: Perfect for handling the varied glassware from banquets, events, and  room service efficiently and  safely.
  • Event Hire Companies: Essential for protecting your glassware inventory during transport and  on-site cleaning, reducing replacement costs.
  • Large Restaurants & Bistros: A must for kitchens with diverse menus that require different types of glassware for wine, water, and  spirits.
