The Albion 640-4 Road Model sets foam backer rod into saw-cut and expansion joints at a consistent depth, which is what makes the sealant bead the right shape. Push the rod in as you walk the joint instead of poking it down by hand.
The reinforced resin handle stands up to abrasive pavement work, and the roller guides keep the rod depth even across long runs of slab and road joints.
Frequently Asked Questions About 640-4 Road Model Kit
Q: What kind of foam backer rods can I use with this tool?
A: The 640-4 Road Model is compatible with most standard foam backer rods, including closed-cell, open-cell, and hybrid variants. Select the matching insertion wheel for your joint size.
Q: How do I adjust the insertion depth?
A: The kit includes four wheels (1/8", 1/4", 3/8", 1/2"). Swap the wheel based on joint width, and manually adjust handle pressure to insert rod up to 1” deep.
Q: Can I use any extension pole?
A: Yes, it accepts any standard threaded broom handle or painter's pole. We recommend Adheseal 876-1 or 876-2 for best fit and durability.
Q: Will it work on vertical surfaces?
A: No. This model is optimised for horizontal surfaces like roads, driveways, and slab joints. Use handheld inserters for vertical joints.
Q: Does it puncture the foam rod?
A: No. It’s specifically designed to set the rod without puncture or tearing, which is critical for forming proper sealant backing.
