Top Post Flexible Military Spec Battery Terminal Cover, Battery Terminal Clamp Insulator Protector W/Washers for Car, Vehicle, RV and Boat (1 Pair)

These are cut for military spec battery terminals, and the supplier prints the exclusion in capitals: NOT standard battery terminals. Moulded rubber offers no adjustment, so that decision is made at the moment you order, and if your battery wears ordinary top-post clamps nothing further down this page changes the answer.

Military spec, and what that word rules out

The exclusion is the fitment story here, and it is worth repeating because the search summary above these words leaves it out entirely and describes the product simply as a cover for top-post terminals. It is not that. The supplier ties the part to military spec terminals again and again, and puts in capitals the one kind it is not for. Measure your own terminal against the inner dimensions below before you buy, because a cover that will not stretch over the clamp is no use at all.

Sold as an insulator, with no insulating figure

The part is described as protecting connections from incidental shorting and from corrosion, and the supplier's own qualifier there is worth keeping: incidental. Against that, the description offers no dielectric strength, no voltage rating, no temperature range for the rubber and no standard it was tested to. An insulator with no insulation figure is being sold on its shape rather than on its electrical performance, and the shape is all we can honestly report.

Key features

• Covers, one pair: red and black, flexible rubber, for top post military spec terminals.
• Washers, one pair: red and black again, supplied alongside the covers.
• Cable entry at the open end: the large end takes cable up to 4/0 gauge.
• Rubber that stretches: the supplier says the flexibility is what lets it hold a military spec terminal.
• Colour-coded by polarity: red and black, so positive and negative stay legible under the bonnet.
• Shorting and corrosion: both are named as what the cover keeps off the connection.

Read these before ordering

• Not for standard battery terminals. The supplier capitalises that restriction; the search summary above drops it and reads as though any top post would do.
• No dielectric strength, no voltage rating, no temperature range and no test standard is given for a part sold to insulate. That is the largest hole in this listing.
• The supplier quotes inches only. The millimetre figures above are our conversions of its numbers, not values it published.
• Under the supplier's own labelling the second width, 2.36 inches, comes out larger than the length, 2.1 inches. Either a label or a figure is wrong at source, and we have reproduced them as given rather than reordering them.
• A brand name has been stripped out of the supplier's fitment sentence, so the particular terminals these were shaped around go unnamed. Work from the measurements, not from a make.
• The description contains no fitting instructions of any kind, and the supplier's word for the protection it offers is incidental, not absolute.

Rubber boots and washers for military spec posts, judged best by holding a tape over your own terminal before the order goes in.
