Plate Holder Extender
Selecting 5/8"? Same Extender, different bolts. Ships with a 5/8" adapter kit and matched hardware to fit your rack's smaller holes.
For Squat Racks
Push flush to the wall
For Plate Trees
Double your plate holders
Plates Face Forward
Load from the front, not the side
Fits 5/8" or 1" Holes
Hardware matched to your rack
An elbow attachment that rotates plate storage 90 degrees so plate holders point forward instead of out to the side. Mount it to a squat rack to push flush against the wall, or add it to your Synergy plate tree to convert side-facing storage into forward-facing (or double your plate holders on either side). Bolts on through your existing rack or tree holes.

Designed & Built in Florida
Every rack is made to order and manufactured in-house to ensure premium quality.
For Your Squat Rack
Push your squat rack flush against the wall. Standard side-mounted plate holders force a 6-12 inch wall gap for plate clearance. The Extender rotates them forward, closing that gap so your rack sits tight to the wall and you reclaim the floor space.
For Your Plate Tree
Add the Extender to your existing Synergy plate tree to convert side-facing storage into forward-facing, or double your plate holders on a tree that already has some. Either way, more capacity in the same footprint. Great for busy home gyms outgrowing their current setup.
Plates Right Where You Want Them
Forward-facing plates load and unload from the front of your rack, so you grab your next plate from a natural, comfortable angle instead of reaching around the side. Small change, big daily improvement.
Build It Your Way
Already own plate holders? Order the Extender on its own. Or have it arrive ready to load by adding one plate holder, or doubling up with plate holders on both sides. Pick your configuration when you order.
Hardware Matched to Your Rack
Select whether your rack's holes are 5/8" or 1" when you order and we include the correct mounting hardware. Everything bolts up the first time. No trips to the hardware store, no adapter kits.

Match it to your rack's mounting hole size.
1" Holes: Synergy racks and most premium 3x3 uprights use 1" mounting holes.
5/8" Holes: Rogue Monster Lite and some REP Fitness and Sorinex models use 5/8" holes.
Not sure which your rack has? Measure the diameter of one of your rack's mounting holes with a ruler or caliper, or check the manufacturer's spec sheet. We include the correct bolts and hardware based on the variant you pick.

Any 3x3 or 2x3 upright with 5/8" or 1" mounting holes on 2" centers (the industry-standard pattern). That covers:
Squat racks: Synergy, Rogue Monster Lite, REP Fitness, Titan, Sorinex, and most premium brands.
Synergy plate trees: the Vertical Plate Storage Tree, Delta PLT, and Delta PK all accept the Extender through their existing hole pattern.

Yes. You can order the Synergy PLH1 Plate Holder any time and attach it to the Extender using the same mounting hardware pattern. Just make sure your Extender variant and plate holder variant match on hole size.
Direct-mount plate holders point out to the SIDE of your rack or tree. That works but comes with tradeoffs:
On a squat rack: plates need side clearance to load, forcing you to pull your rack 6 to 12 inches away from the wall. The Extender rotates the holders 90 degrees to point forward instead, so your rack sits flush.
On a Synergy plate tree: side-facing holders limit access from the front. The Extender lets you add forward-facing holders in addition to (or instead of) side-facing ones, so you can double your storage OR reorient it for easier loading.

Designed for the vertical uprights (the tall columns). On a squat rack, that means the side face of the upright. On a Synergy plate tree, that means the main vertical post. Both positions let the Extender rotate the plate holders forward. Mounting on horizontal bases is not recommended.
Yes. If your plate tree already has side-facing plate holders, you can add an Extender to the same upright and mount an additional plate holder (or two) facing forward. That effectively doubles your plate holder count without buying a second tree. Pick the Extender variant that matches your tree's hole size (5/8" or 1"), and pick the configuration that includes 1 or 2 plate holders unless you already have spare holders on hand.
Limited Lifetime warranty on the steel and powder coat finish. We also offer a 30-day return window from delivery if you change your mind.
