Backer Rods

Image of Attribute. Front orientation. Contains Annotated, Border.

Provide support for sealants in gaps—insert these backer rods into gaps and fill in with sealant.

Closed-Cell Foam—Closed-cell backer rods restrict moisture from being absorbed. Use them with joints that have wide, even spaces.

Open/Closed-Cell Foam—Open/closed backer rods are more compressible than closed-cell ones. They also restrict moisture from being absorbed. Use them with uneven joints where self-leveling is needed.

Open-Cell Foam—Open-cell backer rods are the most compressible and maintain their shape better than open/closed ones. They allow moisture to be absorbed. Although they withstand environments up to 500° F, they shouldn’t be used with hot-pour sealants, which can seep through the large cell size and damage the underlying surface.

Cross-Linked Polyethylene Foam—Cross-linked polyethylene backer rods can be used with tar, asphalt, cement, and other hot-pour sealants.

Caulk Guns


Style A	Style B

Style E	Style F

Style G	Style H

Dispense sealants from cartridges with ease and control.

Ratchet—Ratchet-Mechanism guns only apply pressure to the cartridge while you pull the trigger. They’re good for use with thin materials that require flow control.

Smooth—Smooth-Mechanism guns apply more consistent pressure to the cartridge, so flow continues between trigger pulls. These guns are often used with thick materials that require strength to dispense and maintain flow.

Adjustable Thrust Ratio—Guns with an adjustable thrust ratio let you use the same gun for sealants and caulks with different consistencies. Use a higher thrust ratio to evenly dispense thicker, more viscous sealants and a lower ratio for thinner sealants.

Dual Cartridge Capacity—Guns with a dual cartridge capacity give you more time between refills and let you mix two-part compounds.

Thrust Ratio—To choose a thrust ratio, consider the thickness of the material—thinner materials such as silicone and latex flow easily, so choose a low thrust ratio gun. Thick materials such as urethanes and epoxies require more power to dispense, so choose a high thrust ratio.

Backer Rod Insertion Tools


Insertion Tool with Threaded Handle (Backer Rod Not Included)	Insertion Tool with Backer Rod Holder (Backer Rod Not Included)

Quickly set foam backer rods (not included) in caulk joints at a consistent depth without puncturing them.

Threaded Handle—Tools with a threaded handle are small enough to be kept in your tool kit, making them good for quick jobs with short runs of backer rod. To make them more ergonomic, add a pole handle so you can stand while installing a backer rod on the ground.

Backer Rod Holder—Tools with a backer rod holder are ideal for inserting long runs of backer rod quickly. They keep your backer rod organized and positioned, so you can press it into place with just one pass.

Empty Cartridges for One-Part Adhesive Dispensing Guns

Compact Caulk Guns

Unlike standard caulk guns, these guns measure just 4" long and don’t have a cartridge rod, so you can use them in snug spaces and around tight corners. A built-in cartridge cutter lets you shorten caulk cartridges as you work, making these guns even more compact.
