Peachtree Uni Style Fence Upgrade
The Uni Style Table Saw Fence is a heavy-duty, single-piece aluminum extrusion engineered for strength. It acts as an upgrade to the factory Delta Uni-fence system, addressing limitations of the stock fence for specialized cuts. A key feature is the included UHMW sacrificial face, which enables clean rabbets and easier setup when using jigs and fixtures. The front of the fence is recessed to accept the 1/2″ thick UHWM face, making it straightforward to cut a sacrificial surface to length and shape as needed. This design supports a modular workflow, letting you adapt the fence with additional accessories and stop systems to expand what you can accomplish on a Delta UniFence-equipped saw.
- Heavy-duty aluminum construction for rigidity
- Designed to upgrade Delta UniFence systems
- Includes a 1/2″ UHMW sacrificial fence face
- Supports custom jigs, feathers, and holds for enhanced versatility
The fence is well-suited for users who routinely perform rabbet cuts or need to mount auxiliary fixtures. Its substantial profile helps maintain alignment as you add accessories, contributing to repeatable results across tasks like dados, rabets, and extended cross-cuts. Proper installation on compatible UniFence systems yields consistent fence alignment, which translates to more precise planing and joinery work in shop settings.
BOW XT XTENDER 36” Fence
The XT XTENDER 36” Fence from BOW Products is a versatile add-on designed to work with a range of saws, including portable and benchtop models. Standing about 5 inches tall, it features three top T-slots for feed-control accessories and dedicated clamp slots for multi-position setups. A special slot accepts the BOW Feed Supports accessory and it also includes a dedicated slot for Delta UniFence and Harvey fences, enabling quick compatibility with established fence systems. The fence’s robust aluminum extrusion is finished with anodization for durability and long service life.
- Three top T-slots for diverse accessories
- Clamps and slots tailored for universal setup
- Can attach to Delta UniFence and Harvey fences
- Extends table surface with optional feed supports
Pairing the XTENDER with feed supports allows you to extend the working surface, improving material control for infeed and outfeed operations. This reduces kickback risk and helps maintain squareness across longer cuts. Fast attachment and detachment make it practical for job-site use, and its compatibility with various fences broadens its applicability across different saw brands and setups.
BOW XT XTENDER 46” Fence
The 46” XTENDER fence provides a longer reach for wider workpieces, while retaining the same design language as the 36” model. It includes the top T-slots and clamp slots that enable flexible mounting of accessories, along with a slot compatible with Delta UniFence and Harvey fences for quick integration with existing setups. The aluminum extrusion offers rigidity and an anodized finish for durability in tough shop environments. This fence is well-suited for cabinet saws and larger benchtop setups where extended support and precise control over the workpiece are crucial.
- Longer 46” length for wider panels
- Three top T-slots and multi-position clamps
- Quick-attach capability to Delta UniFence and Harvey fences
- Robust aluminum construction with durable finish
With integrated features for extending the fence surface, this XTENDER helps stabilize longer cuts and improve control, particularly for sheet goods or wider boards. The 46” model is a strong pick for users who regularly tackle larger workpieces or who want the flexibility to configure multiple jigs while maintaining consistent squareness to the blade.
Dewalt OEM Replacement Fence (DWE7485)
This fence is positioned as an OEM replacement for the Dewalt DWE7485, offering a direct, compatible solution when the original fence wears or becomes inaccurate. The listing notes a one-year warranty and identifies the part number N878752 as the replacement. For Dewalt users who rely on consistent alignment and minimal downtime, this option provides a straightforward path to restoring factory-level performance without replacing the entire saw or adopting a more complex aftermarket system. The fit and finish align with the Dewalt design, supporting dependable results on everyday crosscuts and rip cuts.
- OEM replacement for DWE7485
- Part number N878752
- One-year warranty
- Designed for direct compatibility and reliable accuracy
Though targeted at a Dewalt configuration, the principle of a precise, sturdy fence remains universal. Users upgrading from a worn fence or seeking a clean, factory-matched replacement can expect improved stability and repeatable alignment for standard and light-duty cabinet saw tasks.
AUTOVIC Table Saw Fence Rail Upgrade
The AUTOVIC rail upgrade is a practical accessory for existing table saw fences, offering ABS plastic construction for long-term use. It is designed to fit R4512 and R4520 table saw models, addressing common issues like gaps between rails and fences and back-end wobble. The upgrade also strengthens the tensioner, improving overall fence stability. This option is particularly appealing for woodworkers seeking a cost-effective way to restore or improve fence performance without replacing the entire fence system.
- ABS plastic rail upgrade for durability
- Compatible with R4512 and R4520 saws
- Eliminates gaps and reduces rear wobble
- Stronger tensioner for consistent alignment
For users with older saw models, the AUTOVIC upgrade offers a viable route to restore precision and consistency. The included features focus on improving stability and ease of use, which can translate into better joinery outcomes and less fiddling with adjustments between cuts.
Buying Guide
Choosing the right aftermarket fence depends on your saw type, project needs, and shop workflow. Start by confirming compatibility: is your saw portable, benchtop, or cabinet, and does the fence attach to your existing system (Delta UniFence, Harvey fences, or similar)? Fence length should match typical workpieces. Longer fences provide more support but can introduce weight and setup complexity; shorter fences can be quicker to deploy for small projects.
Material and durability matter for long-term accuracy. Aluminum fences offer rigidity with light weight, while sacrificial faces made of UHMW or wood add versatility for rabbet cuts and joinery. If you frequently perform rabbets, dadoes, or extended infeed/outfeed operations, a fence that supports removable or replaceable sacrificial faces is advantageous. Consider fences with integrated T-slots or clamp slots for accessory versatility—jigs, stops, and feather boards become easier to manage and align.
Installation and maintenance should also drive your choice. Quick-attach features and compatible clamps reduce downtime, while a fence with a robust alignment mechanism helps maintain accuracy across sessions. For older or budget saws, rail upgrades and OEM replacements can restore precision without a full fence replacement. Finally, warranty matters: a longer warranty indicates confidence in a fence’s longevity and your protection against defects during heavy use.
