Corrosion Block in this case of 24 supplies 24 separate 4 oz pump spray bottles, identified by SKU 76729 and listed case code 20002CASE. A case of twenty-four compact 4 oz pump sprays for distributing individually identified containers across maintenance locations. Select the package by the work you plan to do and the way you want to dispense the product, while keeping the exact formula instructions with the maintenance supplies.

Corrosion Block is a corrosion-inhibiting fluid designed to penetrate affected areas, displace moisture and leave a protective film. Manufacturer literature describes spray, brush and wipe application for appropriate surfaces. That makes the delivery format an important purchase choice: a pump, aerosol and refill container offer different ways to supply the same maintenance task without establishing that every surface or electrical assembly should be coated.

The case contains twenty-four separate 4 oz pump spray bottles. That format lets a maintenance program place individual bottles at several work locations without treating one pictured bottle as the full order. One cart unit is one case. Keep the bottle instructions available wherever the supply is distributed, and compare the single-bottle listing if the full carton is more than you need.

Manufacturer guidance identifies metal protection and electrical-component applications. Confirm the exact equipment, materials and application location; isolate electrical power before servicing and follow the equipment procedure. Inspect the treated component as part of regular maintenance and plan further care from its condition and exposure. Compare like-for-like formula and package choices before judging the size of the supply.

You can also review the second comparison option. Pump, aerosol, jar and refill formats have different handling and placement considerations.
